QGLviewer is indeed found, at least the release version, that can be used 
also 
in Debug builds (on Linux the distribution usually do not ship debug 
versions, 
but only the release version, plus separate debug symbols).

That is fine.

Same: QtOpenGL is found, and the library is is /usr/lib/x86_64-linux-gnu/.

Really strange. Have you started the CMake configuration from an empty cache? 
Could it be that libQtOpenGL.so was in /usr/lib/ in a previous version of 
your 
Linux distribution, and you have not cleared the CMake cache since?
