Merged requested to merge mmuetzel/cmake:glew into master
When GLEW is found by
find_package, (most of) the variables described in the documentation of
FindGLEW 1 aren't set. That could lead to issues when building packages that rely on these variables.
This PR basically uses the same logic that vcpkg is using to populate these variables. 2 IANAL, but their license should be compatible afaict.
Fixes #19662 (closed)
