Summary0010632: FindQt4.cmake - QT_INCLUDE_DIR is wrongly set on mac os x (bundles)
DescriptionThe QT_INCLUDE_DIR variable is set to:
/opt/local/libexec/qt4-mac/include;/opt/local/libexec/qt4-mac/lib/QtCore.framework

But it should be only the:
/opt/local/libexec/qt4-mac/include


Related output of the sample CMakeConfig.txt (attached):

-- Looking for Q_WS_X11 - not found.

-- Found Qt-Version 4.6.2 (using /opt/local/bin/qmake)
-- Found OpenSSL: /usr/lib/libssl.dylib;/usr/lib/libcrypto.dylib
-- QT_INCLUDE_DIR: /opt/local/libexec/qt4-mac/include;/opt/local/libexec/qt4-mac/lib/QtCore.framework


it looks like it's all done in this code (FindQt4.cmake):

  # If Qt is installed as a framework, we need to add QT_QTCORE_LIBRARY here (which
  # is the framework directory in that case), since this will make the cmake include_directories()
  # command recognize that we need the framework flag with the respective directory (-F)
  IF(QT_USE_FRAMEWORKS)
    SET(QT_INCLUDES ${QT_INCLUDES} ${QT_QTCORE_LIBRARY} )
    SET(QT_INCLUDE_DIR ${QT_INCLUDE_DIR} ${QT_QTCORE_LIBRARY} )
  ENDIF(QT_USE_FRAMEWORKS)

I don't understand mac's frameworks too much but I don't see any reason why there should be QT_QTCORE_LIBRARY listed in includes related variable.

Additional InformationI'm using Qt4 (qt4-mac) and cmake from macports.

 That was done on purpose. How is it a problem for you?

 I'm working on software (kdebindings and its derivates) which uses this variable as path to the include files to parse with its internal tool.

Of course it can be workarounded but I thought that this variable should point to the include dir only. Frameworks should go with libs related variables, shouldn't they?

But as I said - I'm newbie in the mac world.

cmake cfg file:
http://websvn.kde.org/trunk/KDE/kdebindings/smoke/qtcore/CMakeLists.txt?revision=1084718&view=markup [^]

to process this template:
http://websvn.kde.org/trunk/KDE/kdebindings/smoke/qtcore/config.xml.cmake?view=markup [^]

the same is for all modules of Qt4 and more libraries (qscintilla etc.)

 On Mac, header files for frameworks go inside the framework. And then there is /opt/local/libexec/qt4-mac/include for other header files.
So really, there are two include paths. One passed to the compiler as
-I/opt/local/libexec/qt4-mac/include, and the other passed to the compiler as
-F/opt/local/libexec/qt4-mac/lib (which is used for finding framework headers).
CMake will create the -F one from /opt/local/libexec/qt4-mac/lib/QtCore.framework
