[osg-users] fatal error: QGLWidget: No such file or directory‏

You mean cmake ../OpenSceneGraph/ -DQT_QMAKE_EXECUTABLE="/path/to/Qt/5.5/gcc_64/bin/qmake"? I do not think it worked because I got this:

-- Configuring done
-- Generating done
CMake Warning:
  Manually-specified variables were not used by the project:

    QT_QMAKE_EXECUTABLE

I'm using -DQT_QMAKE_EXECUTABLE="/path/to/qmake", and letting cmake do the rest, the cmake documentation for 'FindQt4.cmake' or 'FindQt5.cmake' should also be helpful as it's the 'correct' way to do things

How can I point the OSG build to use the Qt package I installed on my user instead of the system wide one? Is it something about QT_INSTALL_PREFIX?

 Ah, I think qtopengl is in a separate package, try libqt4opengl-dev or libqt5opengl-dev

As for which version you need I know OSG can build against either, but I've only ever tried with 4.

Hello, the CMakeCache.txt do not have QT_QTOPENGL_INCLUDE_DIR or QT_QTOPENGL_LIBRARY.
I used the Linux Mint / Ubuntu apt-get qtbase5-dev package.

I can try to build qt instead. Do I need qt version 4 or 5?
