The nixGL command that `lib.nixGL.wrap` should wrap packages with.
This can be used to provide libGL access to applications on non-NixOS systems.
The [nixGL](https://github.com/nix-community/nixGL) command that `lib.nixGL.wrap` should prefix
package binaries with. nixGL provides your system's version of libGL to applications, enabling
them to access the GPU on non-NixOS systems.
Wrap individual packages like so: `(config.lib.nixGL.wrap <package>)`. The returned package
can be used just like the original one, but will have access to libGL. If this option is empty (the default),
then `lib.nixGL.wrap` is a no-op. This is useful on NixOS, where the wrappers are unnecessary.
Wrap individual packages which require GPU access with the function like so: `(config.lib.nixGL.wrap <package>)`.
The returned package can be used just like the original one, but will have access to libGL. For example:
```nix
# If you're using a Home Manager module to configure the package,
# pass it into the module's package argument:
programs.kitty = {
enable = true;
package = (config.lib.nixGL.wrap pkgs.kitty);
};
# Otherwise, pass it to any option where a package is expected:
home.packages = [ (config.lib.nixGL.wrap pkgs.hello) ];
```
If this option is empty (the default), then `lib.nixGL.wrap` is a no-op. This is useful for sharing your Home Manager
configurations between NixOS and non-NixOS systems, since NixOS already provides libGL to applications without the
need for nixGL.
