Previously the cmake code would try to run the LIBDIR specific "findX.cmake" files for both vulkan and shaderc. However these would pick up system headers and libraries when LIBDIR were not present. This would lead to compilation errors as the system library configurations were not taken into account or queried. This changes it so that if LIBDIR is not present, the proper pkgconfig files will be used instead. Pull Request: https://projects.blender.org/blender/blender/pulls/114639
