Update `BUNDLE_DEPENDENCIES` description with removal of UTF-CPP We no longer use UTF8-CPP, so the mention of it should be removed. Also, I conjoined the two phrases with a semicolon; it flows better.

option(BUNDLE_DEPENDENCIES "Use bundled TinyXML-2, PhysicsFS, and FAudio (if disabled, TinyXML-2, PhysicsFS, and FAudio will be dynamically linked; LodePNG and C-HashMap will still be statically linked)" ON)
Add option to not use bundled TinyXML-2, PhysFS, and UTF8-CPP If you configure the build with -DBUNDLE_DEPENDENCIES=OFF, then VVVVVV will dynamically link with TinyXML-2 and PhysicsFS instead of using the bundled source code in third_party/ and statically linking with them. Unfortunately, it doesn't seem like distros package LodePNG, and LodePNG isn't intended to be packaged, so we can't dynamically link with it, nor can we use some system LodePNG header files somewhere else because those don't exist. UTF8-CPP is a special case, because no matter what, it's going to be statically linked with the binary (it doesn't come as a shared object file in any way). So with -DBUNDLE_DEPENDENCIES=OFF, we will use the system UTF8-CPP header files instead of the bundled ones, but it will still be statically linked in with the binary. The main motivation for doing this is so if VVVVVV ever gets packaged in distros, distro maintainers would be more likely to accept it if there was an option to compile the game without bundled dependencies. Also, it discourages modifying the third-party dependencies we have, because it's always possible for someone to compile those dependencies without our changes, with this CMake option.

Change cache bool variables into options They're the same thing, but using option() better conveys intent. However this can't be done for anything that isn't a bool, which the CUSTOM_LEVEL_SUPPORT option is not (it's a tri-state string).

option(STEAM "Use the Steam API" OFF)
option(GOG "Use the GOG API" OFF)
Allow for conditional building of Steam and GOG APIs I think it's a bit silly to always include the Steam and GOG APIs whenever we build VVVVVV, since the only time they'll ever be used is in a live build and not a dev build. So now Steam and GOG are disabled by default. If you want them, you'll need to add -DSTEAM=ON or -DGOG=ON respectively at CMake time. They're also both automatically enabled for release builds.

Replace release mode conditional with OFFICIAL_BUILD There are probably going to be situations where we'll want to compile in release mode, but still want the hash and don't want Steam/GOG enabled. So Ethan can use OFFICIAL_BUILD when tagging major versions of the game.

option(MAKEANDPLAY "Compile a version of the game without the main campaign (provided for convenience; consider modifying MakeAndPlay.h instead" OFF)
Add official, M&P, no custom levels, and no editor builds to CI CI builds were added to this repository on the first day it was released, and haven't really been touched since then. And since then, 2.3 has added NO_CUSTOM_LEVELS, NO_EDITOR, and OFFICIAL_BUILD builds to the CMake file. On top of the MAKEANDPLAY define already existing, this means CI coverage is a bit sparse - covering compile failures for changes made to most of the codebase, except for Steam and GOG, and not covering compile failures if certain parts of the code get stripped out. And people do forget to check for those configurations as well. These mess of configurations is kind of a wake-up call to refactor and generalize the code a bit, because we would probably be able to get rid of at least two of these (Make & Play, and no-custom-levels) by making it so custom levels behave indistinguishably from the main game. But, that's something to do in 2.4. At the very least, we should cover these in CI right now. On a small note, I had to add a MAKEANDPLAY configure option to the CMake file to be able to easily configure a Make & Play build from the CI runner. This option shouldn't really be used otherwise, so I added a note to it telling people to consider modifying MakeAndPlay.h instead.

Add `REMOVE_ABSOLUTE_PATHS` CMake option This option is enabled by default and will replace absolute paths of all source directory file paths with relative paths in the compiled binary, if the compiler supports it. Of course, this isn't needed if you compile with all paths removed anyways (e.g. in Release mode). The purpose is to help make builds reproducible and to remove any potentially sensitive information about the user or the user's system from the compiled binary. Both Clang and GCC support -fdebug-prefix-map, -fmacro-prefix-map, and -ffile-prefix-map. In particular, -ffile-prefix-map is just a flag that does both -fdebug-prefix-map and -fmacro-prefix-map. According to https://reproducible-builds.org/docs/build-path/ , -fdebug-prefix-map is available in all GCC versions but only available starting from Clang 3.8, and -fmacro-prefix-map and -ffile-prefix-map are available since GCC 8 and Clang 10. So we check the compiler version and use the available flags depending on if the compiler supports it or not. This does make debugging a bit more annoying, but there are a couple ways to rectify this. Either disable it with -DREMOVE_ABSOLUTE_PATHS=OFF, or add a `.gdbinit` that consists of set substitute-path . ../.. so that `.` is considered to be `../..`. Of course, if you need to, replace `../..` with the actual source directory path (in my case it's `../../..` because I place my build folders in another subdirectory to have multiple build folders in one directory). This doesn't need to be a global `.gdbinit`, it can be in a directory-specific `.gdbinit` (similar to how `.gitignore`s can also be directory-specific). But then you need to add `add-auto-load-safe-path` to your `.gdbinit` to load any directory-specific `.gdbinit`s. The above is for GDB; I don't know what (if anything) needs to be done for LLDB; I don't use LLDB. Fixes #889.

Do not hardcode default macOS SDK path Doing this is not necessary as CMake already looks up the default one correctly and in fact breaks whenever you have multiple Xcode versions installed so Xcode is not called Xcode.app. (And it does not respect the default Xcode set using xcode-select) The behavior now is to respect CMAKE_OSX_SYSROOT if set by the user on the command line. If it's not set, try to use the hardcoded path to the 10.9 SDK if it's present. If not, warn about the fact that a different SDK is used.

Use RPATH for lib folder, use PHYSFS_getBaseDir on all platforms. The next official VVVVVV build removes 32-bit Linux (like all my other games), and I need to get rid of the shell script on macOS at some point, so this basically brings it up to what my other games are doing. Plus, this probably fixes a bug where someone tries to run their executable away from the root...

Add support for button glyph display This adds a function that converts an action (such as interacting in-game) to the corresponding button text ("ENTER", "E") or button glyph (PlayStation triangle, Steam Deck Y, etc). This function currently only gives the existing ENTERs or Es, because I don't know how best to detect controller usage, or whether the game is running on a Steam Deck, or what buttons need to be displayed there. Still, it should now be really easy to adapt the rendering of keyboard keys to consoles, controllers, or rebound keys. To identify the actions that currently need to be displayed, this commit also adds the initial enums for action sets as described by Ethan in a comment in #834 (Jan 18, 2022).

Implement new string formatting system (VFormat) This commit adds a new string formatting system to replace uses of `SDL_snprintf` and string concatenation. Making our own string formatting system has been briefly discussed during the review of the localization branch, and on the VVVVVV Discord. It's inspired by Python's format strings, but simpler. This is primarily to benefit localization - strings will be easier to understand (`Now using %s Tileset` → `Now using {area} Tileset`, `"%s remain"` → `"{n_crewmates|wordy} remain"`), translators can change the word order for their language's grammar (`%1$s` is a POSIX extension), and this system is also less error-prone (making the format string not align with the actual arguments won't result in a crash or UB). It also integrates our needs better - particularly the "wordy" numbers without having to have a `help.number_words(n).c_str()` at the callsite, translators can opt in and out of wordy numbers per string, and this should also make it easier to solve #859. This commit adds the formatting system itself, and changes one `SDL_snprintf` in the code to use it as a small demo (the rest should probably be done in the localization branch to avoid more unneeded work). The system is described in full detail in VFormat.h and in the pull request description.

Start rewrite of font system This is still a work in progress, but the existing font system has been removed and replaced by a new one, in Font.cpp. Design goals of the new font system include supporting colored button glyphs, different fonts for different languages, and larger fonts than 8x8 for Chinese, Japanese and Korean, while being able to support their 30000+ characters without hiccups, slowdowns or high memory usage. And to have more flexibility with fonts in general. Plus, Graphics.cpp was long enough as-is, so it's good to have a dedicated file for font storage. The old font system worked with a std::vector<SDL_Surface*> to store 8x8 surfaces for each character, and a std::map<int,int> to store mappings between codepoints and vector indexes. The new system has a per-font collection of pages for every block of 0x1000 (4096) codepoints, that may be allocated as needed. A glyph on a page contains the index of the glyph in the image (giving its coordinates), the advance (how much the cursor should advance, so the width of that glyph) and some flags which would be at least whether the glyph exists and whether it is colored. Most of the *new* features aren't implemented yet; it's currently hardcoded to the regular 8x8 font.png, but it should be functionally equivalent to the previous behavior. The only thing that doesn't really work yet is level-specific font.png, but that'll be supported again soon enough. This commit also adds fontmeta (xml) support. Since the fonts folder is mounted at graphics/, there are two main options for recognizing non-font.png fonts: the font files have to be prefixed with font (or font_) or some special file extension is involved to signal what files are fonts. I always had a font.xml in mind (so font_cn.xml, font_ja.xml, etc) but if there's ever gonna be a need for further xml files inside the graphics folder, we have a problem. So I named them .fontmeta instead. A .fontmeta file looks somewhat like this: <?xml version="1.0" encoding="UTF-8"?> <font_metadata> <width>12</width> <height>12</height> <white_teeth>1</white_teeth> <chars> <range start="0x20" end="0x7E"/> <range start="0x80" end="0x80"/> <range start="0xA0" end="0xDF"/> <range start="0x250" end="0x2A8"/> <range start="0x2AD" end="0x2AD"/> <range start="0x2C7" end="0x2C7"/> <range start="0x2C9" end="0x2CB"/> ... </chars> <special> <range start="0x00" end="0x1F" advance="6"/> <range start="0x61" end="0x66" color="1"/> <range start="0x63" end="0x63" color="0"/> </special> </font_metadata> The <chars> tag can be used to specify characters instead of in a .txt. The original idea was to just always use the existing .txt system for specifying the font charset, and only use the XML for the other stuff that the .txt doesn't cover. However, it's probably better to keep it simple if possible - having to only have a .png and a .fontmeta seems simpler than having the data spread out over three files. And a major advantage: Chinese fonts can have about 30000 characters! It's more efficient to be able to have a tag saying "now there's 20902 characters starting at U+4E00" than to include them all in a text file and having to UTF-8 decode every single one of them. If a font.txt exists, it takes priority over the <chars> tag, and in that case, there's no reason to include the <chars> tag in the XML. But font.txt has to be in the same directory as font.png, otherwise it is rejected. Same for font.fontmeta. If neither font.txt nor <chars> exist, then the font is seen as a 2.2-and-below-style ASCII font. In <special>: advance is the number of pixels the cursor advances after drawing the character (so the width of the character, without affecting the grid in the source image), color is whether the character should have its original colors retained when printed (for button glyphs). As for <white_teeth>: The renderer PR has replaced draw-time whitening of sprites/etc (using BlitSurfaceColoured) by load-time whitening of entire images (using LoadImage with TEX_WHITE as an argument). This means we have a problem: fonts have always had their glyphs whitened at printing time, and since I'm adding support for colored button glyphs, I changed it so glyphs would sometimes not be whitened. But if we can't whiten at print time, then we'd need to whiten at load time, and if we whiten the entire font, any colored glyphs will get destroyed too. If you whiten the image selectively, well, we need more code to target specific squares in the image, and it's kind of a waste when you need to whiten 30000 12x12 Chinese characters when you're only going to need a handful, but you don't know which ones. The solution: Whitening fonts is useless if all the non-colored glyphs are already white, so we don't need to do it anyway! However, any existing fonts that have non-white glyphs (and I know of at least one level like that) will still need to be whitened. So there is now a font property <white_teeth> that can be specified in the fontmeta, which indicates that the font is already pre-whitened. If not specified, traditional whitening behavior will be used, and the font cannot use colored glyphs.

Add Textbook A relevant paragraph copied from the original commit history: The idea is that we store all strings somewhere managed, and then the hashmap only needs pointers to those strings. For storing strings, I created a `Textbook` structure, which consists of one or more 50 KB "pages" (allocated as needed) on which you can simply write strings in both languages back-to-back with `textbook_store(textbook, text)` and get pointers to each of them. (I was originally going to just use one big buffer and realloc to double the size when filled up, but then the hashmap would be full of dangling pointers...) When needed, like when switching to a different language, an entire textbook can be freed at once. This commit is part of rewritten history of the localization branch.

Add UTF8.c This is a small library I wrote to handle UTF-8. Usage is meant to be as simple as possible - see for example decoding a UTF-8 string: const char* str = "asdf"; uint32_t codepoint; while ((codepoint = UTF8_next(&str))) { // you have a codepoint congrats } Or encoding a single codepoint to add it to a string: std::string result; result.append(UTF8_encode(0x1234).bytes); There are some other functions (UTF8_total_codepoints() to get the total number of codepoints in a string, UTF8_backspace() to get the length of a string after backspacing one character, and UTF8_peek_next() as a slightly less fancy version of UTF8_next()), but more functions could always be added if we need them. This will allow us to replace utfcpp (utf8::unchecked) and also fix some less-than-ideal code: - Some places have to resort to ignoring UTF-8 (next_wrap) or using UCS-4→UTF-8 functions (VFormat had to use PHYSFS ones, and one other place has four lines of code including a std::back_inserter just for one character) - The iterator stuff is kinda confusing and verbose anyway

Implement new string formatting system (VFormat) This commit adds a new string formatting system to replace uses of `SDL_snprintf` and string concatenation. Making our own string formatting system has been briefly discussed during the review of the localization branch, and on the VVVVVV Discord. It's inspired by Python's format strings, but simpler. This is primarily to benefit localization - strings will be easier to understand (`Now using %s Tileset` → `Now using {area} Tileset`, `"%s remain"` → `"{n_crewmates|wordy} remain"`), translators can change the word order for their language's grammar (`%1$s` is a POSIX extension), and this system is also less error-prone (making the format string not align with the actual arguments won't result in a crash or UB). It also integrates our needs better - particularly the "wordy" numbers without having to have a `help.number_words(n).c_str()` at the callsite, translators can opt in and out of wordy numbers per string, and this should also make it easier to solve #859. This commit adds the formatting system itself, and changes one `SDL_snprintf` in the code to use it as a small demo (the rest should probably be done in the localization branch to avoid more unneeded work). The system is described in full detail in VFormat.h and in the pull request description.

Optimize recompilation from changing commit hash This reworks how the commit hash and date are compiled so that if they're changed (and they're changed often), only one source file needs to be recompiled in order to update it everywhere in the game, no matter how many source files use the hash or date. The commit hash and date are now declared in InterimVersion.h (and they need `extern "C"` guards because otherwise it results in a link fail on MSVC because MSVC is stupid). To do this, what now happens is that upon every rebuild, InterimVersion.in.c is processed to create InterimVersion.out.c, then InterimVersion.out.c is compiled into its own static library that is then linked with VVVVVV. (Why didn't I just simply add it to the list of VVVVVV source files? Well, doing it _now_ does nothing because at that point the horse is already out of the barn, and the VVVVVV executable has already been declared, so I can't modify its sources. And I can't do it before either, because we depend on the VVVVVV executable existing to do the interim version logic. I could probably work around this by cleverly moving around lines, but that'd separate related logic from each other.) And yes, the naming convention has changed. Not only did I rename Version to InterimVersion (to clearly differentiate it from ReleaseVersion, which I'll be adding later), I also named the files InterimVersion.in.c and InterimVersion.out.c instead of InterimVersion.c.in and InterimVersion.c.out.

Update commit hash every time it changes, not just when CMake is re-ran The commit hash is now properly updated every time it gets changed, and not just when CMake gets re-ran. For this to work, we need to use a few CMake tricks. We add a custom target with ADD_CUSTOM_TARGET(), which is apparently always considered out-of-date (but I had to add a BYPRODUCTS line to get it to actually work), and we use the target to run a .cmake file every time we build. Also, VVVVVV needs to depend on this custom target, to ensure that the game gets built AFTER the version gets generated - otherwise there'll be an error. So we do an ADD_DEPENDENCIES() after the ADD_EXECUTABLE() for VVVVVV. This file, version.cmake, is just the Version.h.out generation that I added previously, but the important thing about all of this is that if the contents of Version.h.out doesn't change, and thus if the commit hash hasn't changed, then CMake will never recompile and relink anything at all. (At least with the Ninja generator.) On a small note, since the Version.h.out generation is now a separate script that is guaranteed to get ran on every single build, while the Git FIND_PACKAGE() gets ran only at configure time, it is possible for the cached path of the Git executable to get out of date. Fixing this requires a simple re-configure (ideally), but in case it wasn't fixed, the INTERIM_COMMIT and COMMIT_DATE variables would get set to empty strings instead of containing a value. To prevent this from happening, I've removed ERROR_QUIET from the EXECUTE_PROCESS() calls in version.cmake, because it's better to explicitly error if the Git executable wasn't found than implicitly carry on like nothing happened.

Disable MSVC warnings about implicit conversion Implicit conversion warnings happen all over the codebase, but there's no reason to warn on all of them, and adding casts everywhere is annoying to read and patently unnecessary. MSVC is the only compiler that has this warning (GCC even on -Wall -Wextra doesn't warn about implicit conversions), so disable it for MSVC.

Silence warnings about using `long long` in C++03 We get these warnings because of the typedefs for 64-bit integers in PhysFS's header files. The compiler will treat them as extensions and will still compile it fine but it does mean we aren't strictly standards conforming. Which really isn't a problem anyway. Probably.

Fix C/C++ standards being unset for VVVVVV target if CMake is >= 3.1.3 So, it turns out we weren't quite done fighting CMake yet... To accommodate #869 (and actually also #272), the C standard was raised from C90 to C99. This turned out to require a bit of a fight with the CentOS CI's CMake version to get it to set the flags we wanted (and to not overwrite them later). Eventually the fix was to move the block that sets the standards to later in the file, which was done in 24353a54bb40665b64a93faebfb2ebd96cd0f6b5. As it apparently turns out, if your CMake is at least 3.1.3 and `CMAKE_<LANG>_STANDARD` is used instead of the workaround, the standard setting now has an effect on the third party libraries, but not on VVVVVV itself. The cause is (probably) the phrase "if it is set when a target is created" in the CMake documentation - the `CMAKE_<LANG>_STANDARD` values have to come before the VVVVVV target is defined. In other words, the compiler's default C/C++ standard will be used, probably something like C17 and C++17. As I can confirm with `__cplusplus` and `__STDC_VERSION__` with my recent-enough CMake. If I force the pre-3.1.3 workaround to be used, everything is compiled with C99/C++98 as expected; and the `-fno-exceptions` `-fno-rtti` flags appear everywhere regardless of version. So my fix is to make the CMakeLists a little less complex by simplifying away the `CMAKE_<LANG>_STANDARD` and `CMAKE_<LANG>_EXTENSIONS`, and always using the workaround regardless of CMake version. There's nothing wrong with the workaround, the same thing is also done for `-fno-exceptions` `-fno-rtti`, and it's good to have a less complicated CMakeLists that doesn't do different and unexpected things for different versions.

Add option to not use bundled TinyXML-2, PhysFS, and UTF8-CPP If you configure the build with -DBUNDLE_DEPENDENCIES=OFF, then VVVVVV will dynamically link with TinyXML-2 and PhysicsFS instead of using the bundled source code in third_party/ and statically linking with them. Unfortunately, it doesn't seem like distros package LodePNG, and LodePNG isn't intended to be packaged, so we can't dynamically link with it, nor can we use some system LodePNG header files somewhere else because those don't exist. UTF8-CPP is a special case, because no matter what, it's going to be statically linked with the binary (it doesn't come as a shared object file in any way). So with -DBUNDLE_DEPENDENCIES=OFF, we will use the system UTF8-CPP header files instead of the bundled ones, but it will still be statically linked in with the binary. The main motivation for doing this is so if VVVVVV ever gets packaged in distros, distro maintainers would be more likely to accept it if there was an option to compile the game without bundled dependencies. Also, it discourages modifying the third-party dependencies we have, because it's always possible for someone to compile those dependencies without our changes, with this CMake option.

Reduce dependency on libc functions During 2.3 development, there's been a gradual shift to using SDL stdlib functions instead of libc functions, but there are still some libc functions (or the same libc function but from the STL) in the code. Well, this patch replaces all the rest of them in one fell swoop. SDL's stdlib can replace most of these, but its SDL_min() and SDL_max() are inadequate - they aren't really functions, they're more like macros with a nasty penchant for double-evaluation. So I just made my own VVV_min() and VVV_max() functions and placed them in Maths.h instead, then replaced all the previous usages of min(), max(), std::min(), std::max(), SDL_min(), and SDL_max() with VVV_min() and VVV_max(). Additionally, there's no SDL_isxdigit(), so I just implemented my own VVV_isxdigit(). SDL has SDL_malloc() and SDL_free(), but they have some refcounting built in to them, so in order to use them with LodePNG, I have to replace the malloc() and free() that LodePNG uses. Which isn't too hard, I did it in a new file called ThirdPartyDeps.c, and LodePNG is now compiled with the LODEPNG_NO_COMPILE_ALLOCATORS definition. Lastly, I also refactored the awful strcpy() and strcat() usages in PLATFORM_migrateSaveData() to use SDL_snprintf() instead. I know save migration is getting axed in 2.4, but it still bothers me to have something like that in the codebase otherwise. Without further ado, here is the full list of functions that the codebase now uses: - SDL_strlcpy() instead of strcpy() - SDL_strlcat() instead of strcat() - SDL_snprintf() instead of sprintf(), strcpy(), or strcat() (see above) - VVV_min() instead of min(), std::min(), or SDL_min() - VVV_max() instead of max(), std::max(), or SDL_max() - VVV_isxdigit() instead of isxdigit() - SDL_strcmp() instead of strcmp() - SDL_strcasecmp() instead of strcasecmp() or Win32 strcmpi() - SDL_strstr() instead of strstr() - SDL_strlen() instead of strlen() - SDL_sscanf() instead of sscanf() - SDL_getenv() instead of getenv() - SDL_malloc() instead of malloc() (replacing in LodePNG as well) - SDL_free() instead of free() (replacing in LodePNG as well)

Disable FAudio debug configuration in Release mode Whereas all `SDL_assert`s will go away when compiling with optimization flags and all plain `assert` calls (used in PhysFS) will go away when compiling in Release mode, FAudio has a bunch of debug stuff that needs to be explicitly disabled with its own `FAUDIO`-prefixed flag. To do this in Release mode, we need to use generator expressions for dumb CMake reasons. Basically, if checking the CMAKE_BUILD_TYPE variable will not work for certain generators (Ninja, Visual Studio) because they only specify the build type at build time, not generation/configuration time.

Add `/MT` flag for MSVC This flag makes it so the MSVC runtime libraries are statically linked. This avoids needing Windows users to have these libraries installed. Apparently /MT stands for "MultiThreaded", and there's a bit of a history there where originally by default you could only have a single-threaded library, and then the multi-threaded flags were added in later. First I tried doing target_compile_options on VVVVVV, but then got a linker error. Then I tried doing add_compile_options because I figured /MT had to be applied everywhere, and it seemed to work, but it still linked to the runtime libraries. Apparently it was being overridden. Then I tried target_compile_options again but this time did it to everything, and that linked correctly and also removed the runtime dependency. I would've tried using the MSVC_RUNTIME_LIBRARY property - along with the CMP0091 policy - but those were only introduced in CMake 3.15. You can verify that a binary is built without dependencies by installing LLVM and running llvm-readobj --needed-libs path/to/binary. This is the output for a binary with runtime dependencies: infoteddy@fedorarune  ~/d  llvm-readobj --needed-libs VVVVVV.exe File: VVVVVV.exe Format: COFF-i386 Arch: i386 AddressSize: 32bit NeededLibraries [ ADVAPI32.dll KERNEL32.dll MSVCP140.dll SDL2.dll SHELL32.dll USER32.dll VCRUNTIME140.dll api-ms-win-crt-heap-l1-1-0.dll api-ms-win-crt-locale-l1-1-0.dll api-ms-win-crt-math-l1-1-0.dll api-ms-win-crt-runtime-l1-1-0.dll api-ms-win-crt-stdio-l1-1-0.dll api-ms-win-crt-string-l1-1-0.dll api-ms-win-crt-time-l1-1-0.dll api-ms-win-crt-utility-l1-1-0.dll ] And this is the output for a binary with those dependencies having been statically-linked in: infoteddy@fedorarune  ~/d  llvm-readobj --needed-libs VVVVVV.exe File: VVVVVV.exe Format: COFF-i386 Arch: i386 AddressSize: 32bit NeededLibraries [ ADVAPI32.dll KERNEL32.dll SDL2.dll SHELL32.dll USER32.dll ]

De-duplicate list of static libraries and flags applied to all libraries This is so flags that apply globally (i.e. to the game and all static libraries it's compiled with), such as /MT on MSVC, can be put in a list, and along with putting all static libraries in a list, we remove the need for each flag to be repeated for each static library and we can just use a foreach loop instead. (Global compile flags of course don't apply to us meddling with CMAKE_C_FLAGS and CMAKE_CXX_FLAGS directly, because we need to do that in order to make sure the C and C++ standards are set properly.)

Add `/MT` flag for MSVC This flag makes it so the MSVC runtime libraries are statically linked. This avoids needing Windows users to have these libraries installed. Apparently /MT stands for "MultiThreaded", and there's a bit of a history there where originally by default you could only have a single-threaded library, and then the multi-threaded flags were added in later. First I tried doing target_compile_options on VVVVVV, but then got a linker error. Then I tried doing add_compile_options because I figured /MT had to be applied everywhere, and it seemed to work, but it still linked to the runtime libraries. Apparently it was being overridden. Then I tried target_compile_options again but this time did it to everything, and that linked correctly and also removed the runtime dependency. I would've tried using the MSVC_RUNTIME_LIBRARY property - along with the CMP0091 policy - but those were only introduced in CMake 3.15. You can verify that a binary is built without dependencies by installing LLVM and running llvm-readobj --needed-libs path/to/binary. This is the output for a binary with runtime dependencies: infoteddy@fedorarune  ~/d  llvm-readobj --needed-libs VVVVVV.exe File: VVVVVV.exe Format: COFF-i386 Arch: i386 AddressSize: 32bit NeededLibraries [ ADVAPI32.dll KERNEL32.dll MSVCP140.dll SDL2.dll SHELL32.dll USER32.dll VCRUNTIME140.dll api-ms-win-crt-heap-l1-1-0.dll api-ms-win-crt-locale-l1-1-0.dll api-ms-win-crt-math-l1-1-0.dll api-ms-win-crt-runtime-l1-1-0.dll api-ms-win-crt-stdio-l1-1-0.dll api-ms-win-crt-string-l1-1-0.dll api-ms-win-crt-time-l1-1-0.dll api-ms-win-crt-utility-l1-1-0.dll ] And this is the output for a binary with those dependencies having been statically-linked in: infoteddy@fedorarune  ~/d  llvm-readobj --needed-libs VVVVVV.exe File: VVVVVV.exe Format: COFF-i386 Arch: i386 AddressSize: 32bit NeededLibraries [ ADVAPI32.dll KERNEL32.dll SDL2.dll SHELL32.dll USER32.dll ]

Add `REMOVE_ABSOLUTE_PATHS` CMake option This option is enabled by default and will replace absolute paths of all source directory file paths with relative paths in the compiled binary, if the compiler supports it. Of course, this isn't needed if you compile with all paths removed anyways (e.g. in Release mode). The purpose is to help make builds reproducible and to remove any potentially sensitive information about the user or the user's system from the compiled binary. Both Clang and GCC support -fdebug-prefix-map, -fmacro-prefix-map, and -ffile-prefix-map. In particular, -ffile-prefix-map is just a flag that does both -fdebug-prefix-map and -fmacro-prefix-map. According to https://reproducible-builds.org/docs/build-path/ , -fdebug-prefix-map is available in all GCC versions but only available starting from Clang 3.8, and -fmacro-prefix-map and -ffile-prefix-map are available since GCC 8 and Clang 10. So we check the compiler version and use the available flags depending on if the compiler supports it or not. This does make debugging a bit more annoying, but there are a couple ways to rectify this. Either disable it with -DREMOVE_ABSOLUTE_PATHS=OFF, or add a `.gdbinit` that consists of set substitute-path . ../.. so that `.` is considered to be `../..`. Of course, if you need to, replace `../..` with the actual source directory path (in my case it's `../../..` because I place my build folders in another subdirectory to have multiple build folders in one directory). This doesn't need to be a global `.gdbinit`, it can be in a directory-specific `.gdbinit` (similar to how `.gitignore`s can also be directory-specific). But then you need to add `add-auto-load-safe-path` to your `.gdbinit` to load any directory-specific `.gdbinit`s. The above is for GDB; I don't know what (if anything) needs to be done for LLDB; I don't use LLDB. Fixes #889.
