James Zern e407d4b37c CMakeLists.txt: replace GLUT_glut_LIBRARY w/GLUT::GLUT 
GLUT_glut_LIBRARY is a cache variable that is not recommended for use:

from cmake-3.24/Modules/FindGLUT.cmake:
This module may set the following variables depending on platform.
These variables may optionally be set to help this module find the
correct files, but clients should not use these as results:

...

``GLUT_glut_LIBRARY``
  The full path to the glut library.

based on a patch in the Krita and vcpkg projects:
7d51396a7a/3rdparty/ext_webp/0009-glut.patch
https://github.com/microsoft/vcpkg/blob/master/ports/libwebp/0009-glut.patch
