If my CMakeLists.txt has this find_package(KDE4 REQUIRED) it will first try to find Qt4. Reproducible: Always Steps to Reproduce: 1.try to write a new program for KDE, using cmake to build it 2.run cmake 3.fails with error: QtCore/QtGlobal: No such file or directory 4.add a "message" directive to the bottom of /usr/share/apps/cmake/modules/FindQt4.cmake: message(STATUS "QT4 include dir ${QT_INCLUDE_DIR}") 5.try cmake again Actual Results: -- Found Qt-Version 4.7.0 (using /usr/bin/qmake) -- Found X11: /usr/lib/libX11.so -- QT4 include dir /usr/include -- Phonon Version: 4.4.2 CMake Error at /usr/share/apps/cmake/modules/FindKDE4Internal.cmake:1167 (message): Could not compile simple test program: #include <QtCore/QtGlobal> int main() { #ifdef QT_VISIBILITY_AVAILABLE return 0; #else return 1; #endif } Change Dir: /home/user/myproject/qtcreator-build/CMakeFiles/CMakeTmp Run Build Command:/usr/bin/make "cmTryCompileExec/fast" /usr/bin/make -f CMakeFiles/cmTryCompileExec.dir/build.make CMakeFiles/cmTryCompileExec.dir/build make[1]: Entering directory `/home/user/myproject/qtcreator-build/CMakeFiles/CMakeTmp' /usr/bin/cmake -E cmake_progress_report /home/user/myproject/qtcreator-build/CMakeFiles/CMakeTmp/CMakeFiles 1 Building CXX object CMakeFiles/cmTryCompileExec.dir/check_qt_visibility.cpp.o /usr/lib/ccache/bin/c++ -Wnon-virtual-dtor -Wno-long-long -ansi -Wundef -Wcast-align -Wchar-subscripts -Wall -W -Wpointer-arith -Wformat-security -fno-exceptions -DQT_NO_EXCEPTIONS -fno-check-new -fno-common -Woverloaded-virtual -fno-threadsafe-statics -fvisibility=hidden -I/usr/include/QtXmlPatterns -I/usr/include/QtXml -I/usr/include/QtWebKit -I/usr/include/QtUiTools -I/usr/include/QtTest -I/usr/include/QtSvg -I/usr/include/QtSql -I/usr/include/QtScriptTools -I/usr/include/QtScript -I/usr/include/QtOpenGL -I/usr/include/QtNetwork -I/usr/include/QtMultimedia -I/usr/include/QtHelp -I/usr/include/QtDesigner -I/usr/include/QtDBus -I/usr/include/Qt3Support -I/usr/include/QtGui -I/usr/include/QtCore -I/usr/include/Qt -I/usr/share/qt/mkspecs/default -o CMakeFiles/cmTryCompileExec.dir/check_qt_visibility.cpp.o -c /home/user/myproject/qtcreator-build/CMakeTmp/check_qt_visibility.cpp /home/user/myproject/qtcreator-build/CMakeTmp/check_qt_visibility.cpp:1:27: error: QtCore/QtGlobal: No such file or directory make[1]: Leaving directory `/home/user/myproject/qtcreator-build/CMakeFiles/CMakeTmp' make[1]: *** [CMakeFiles/cmTryCompileExec.dir/check_qt_visibility.cpp.o] Error 1 make: *** [cmTryCompileExec/fast] Error 2 Call Stack (most recent call first): /usr/share/cmake/Modules/FindKDE4.cmake:95 (FIND_PACKAGE) CMakeLists.txt:2 (find_package) -- Configuring incomplete, errors occurred! Expected Results: QT4 include dir should be /usr/include/qt4 on Gentoo
workaround - let cmake see what it's expecting to: cd /usr/include/ ln -s qt4/* .

This helped: cd /usr/include ln -s qt4 Qt since it was using -I/usr/include/Qt for that test.
Could you please attach a simple CMakeLists.txt file from a project that has this problem?!
Maybe the qt guys could have a quick look at this.
No reply for quite some time.
