Force wrap file usage for stb and glm dependencies

[K1ngst0m]

The dependency() for stb and glm first searched for system-installed versions, which could an incompatible version (e.g. stb_image_resize2.h), it may break the build.

By forcing the use of the subproject wrap files, it will prevent breaking changes due to unpredictable system dependency versions.

As a distro packager, this is actually causing new issues for us. I understand the temptation to tightly control dependency versions, but unless there's specific technical reasons for it, we would prefer to build with the shared libraries we already have.

stb and glm are both header only libraries.

Yes, but it is still preferable to use the versions we already ship.

Thanks for the advice. I think it’s better to provide override options for build dependency paths. I’ve added the glm_include_dir and stb_include_dir options in PR #1846.
