我正在使用新的 Ubuntu 13.04 并通过apt-get install. 现在好像安装了qt5。使用 qt5 的 CMake 项目运行良好。
我在 ubuntu 12.04 上安装了 qt4 的机器上运行了相同的代码，并且运行良好。但现在我收到以下错误：（不要担心提升的东西，它来自父 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.

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.

这是我的CMakeLists.txt。有谁知道如何在新的 ubuntu 上同时使用 qt4 和 qt5？提前致谢。
