I could workaround the problem by not removing FindGLEW.cmake anymore since either it was shipped by CMake directly before or something might have changed with recent glew versions and their shipped CMake modules.

[...]
-- Found GLEW: /usr/x86_64-pc-linux-gnu/lib64/cmake/glew/glew-config.cmake
[...]

vs. FindGLEW.cmake shipped with hugin:
[...]
-- Found Glew: /usr/x86_64-pc-linux-gnu/lib/libGLEW.so
[...]

Guess this bug can be closed since it was caused by downstream changes and if you don't intent to rely on the CMake modules shipped with glew in the future.
