Subject: [PATCH] Fix linking of GLEW library

FindGLEW.cmake Module silently tries to include glew-config.cmake.
If it succeeds, then it stop and return to the caller.
However, glew-config.cmake only sets GLEW::GLEW, resulting in
missing glew shared library at link time.

Credits to Eduardo Suarez-Santana for discovering the build error and providing the fix.
