Revert "CMake: better GLX detection" 

This fixes the build when GLX is available.

In the .pro files as well as the .cpp files the condition of enabling
GLX support is based on the Qt feature system (xlib && opengl &&
!opengles2). The change to replace the !opengles check with a cmake
target check is incomplete for two reasons:

    (1) the target check would _never_ succeed because there was no
    find_package() call in scope that would create the target.

    (2) when the target is found, the .cpp code that checks for the
    features would fail, because that continues to use the !opengles2
    condition -- the preprocessor can't know about cmake targets.

So this reverts commit 1361cf5d50 and
instead calls for an investigation why in Ville's machine desktop gl was
disabled.
