assimp build error on ARCH

[kengregson]

Hi,

Thanks for creating Glitter as a helping hand to us beginning OpenGL developers!
Following instructions on ARCH (EndeavourOS) results in compiler warnings (treated as errors) for assimp (in FBXParser.cpp)

While likely less than ideal, build completes with brute force override of assimp cmake OPTION via:
cmake .. -DASSIMP_WARNINGS_AS_ERRORS=OFF
