Acfutils build fails at "TEST_GLSL_VERSION" and "GLEW_ARB_gl_spirv"

[JT8D-17]

After applying bandaids to much of the dependency build process and much of the libacfutils build process (it's been hell on earth so far), I'm stuck.

../src/shader.c: In function ‘shader_from_spirv_fallback’:
../src/shader.c:135:27: error: ‘GLEW_VERSION_4_6’ undeclared (first use in this function); did you mean ‘GLEW_VERSION_4_3’?

The header file chain does eventually point to GL/glew.h as far as I can see and I've pointed qmake/qmake.pro to INCLUDEPATH += ../glew/glew-1.13.0-linux-64/include and applied that potential fix from another issue, i.e. DEFINES += GLEW_STATIC GLEW_MX, but no success.

All I want is to compile a more up to date release of librain...
