Hey @elde-n,

The LWJGL build system is indeed hardcoded to require GCC on Linux. This has always bothered me, but I'm afraid I don't have the energy to address it. Maintaining the native builds of LWJGL and all of its dependencies on Linux has proven to be a living hell for me and I don't want to complicate it any further by adding support for Clang.

Right now at least. LWJGL 4 may provide an opportunity to revisit this.
