Nope. Your library has to link against those libraries. The applications only 
have to if they use this interface directly.

You do TARGET_LINK_LIBRARIES(mylib /path/to/glew/libglew.so). That's all. To 
get the path to GLEW in a system independent way please have a look on 
FIND_LIBRARY.

The only exception is if your library is a static one and the target 
application is not built with CMake. The problem is that you can't put this 
information in static libraries. Writing a pkgconfig or CMake export file is the 
way to go then.
