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. I needed to put the file extension on the end because otherwise CMake wouldn't recognize what kind of language it is, and I mean like yeah duh of course it doesn't, my text editor doesn't recognize it either. 2022-08-23 06:21:23 +02:00			`const char* INTERIM_COMMIT = "@INTERIM_COMMIT@";`
