I am using the new Ubuntu 13.04 and installed qt via apt-get install . It seems that qt5 is installed now. The qake project using qt5 works well.
I had the same code that was running on a machine with qt4 installed on ubuntu 12.04, and it worked fine. But now I get the following error message: (Don’t worry about what happens in boost, it comes from parent CMakeLists.txt)
CMake Error at /usr/share/cmake-2.8/Modules/FindQt4.cmake:619 (message): Could NOT find QtCore. Check /home/simongroth/Projects/pgCrazyMachinesVR/src-build2/CMakeFiles/CMakeError.log for more details. Call Stack (most recent call first): Views/LevelEditor/CMakeLists.txt:32 (FIND_PACKAGE) CMake Warning at /usr/share/cmake-2.8/Modules/FindQt4.cmake:615 (message): /usr/bin/qmake-qt4 reported QT_INSTALL_LIBS as "/usr/lib/x86_64-linux-gnu" but QtCore could not be found there. Qt is NOT installed correctly for the target build environment. Call Stack (most recent call first): Views/LevelEditor/CMakeLists.txt:32 (FIND_PACKAGE)
This is my CMakeLists.txt . Does anyone know how to use qt4 and qt5 simultaneously on new ubuntu? Thanks in advance.
