FindGLUT.cmake: Failing to link statically compile glut on windows with mingw-w64

Related MR for libtiff: https://gitlab.com/libtiff/libtiff/-/merge_requests/233

FreeGLUT compiled from https://github.com/dcnieho/FreeGLUT with mingw-w64 gcc provided by msys2 and the FREEGLUT_REPLACE_GLUT option set to ON and FREEGLUT_BUILD_SHARED_LIBS to OFF provides libglut.a, GL/glut.h, pkgconfig/glut.pc and a few other FreeGLUT related files.

Attempting to use the FindGLUT.cmake module and linking GLUT::GLUT results in undefined references to winmm and opengl32 library functions as GLUT::GLUT does not properly list them as dependencies.

It would probably be preferred to check pkg-config if glut exists and try pulling information from there before checking for the physical files.
