QT_INSTALL_DIR, KDELibsDependencies.cmake and flexible install location of Qt

[Alexander Neundorf]

Hi,

I think on Windows there still was an issue with the KDELibsDependencies.cmake 
file, or more specifically, KDELibs4LibraryTargets-<CONFIG>.cmake, IIRC.

This file contains the dependency libraries for the installed libraries from 
kdelibs, mostly, e.g. for Qt, with the full path to the libraries (as they 
were at kdelibs-cmake time).
Now if Qt is installed in some other location (on Windows), this leads to 
problems when somebody tries to build against this (since the dependencies in 
KDELibs4LibraryTargets-<CONFIG>.cmake point to wrong locations), right ?

I didn't figure out completely how the QT_INSTALL_DIR variable is used here...

Do you still have that problem or did you find some solution/workaround for 
this ?

If not, I think I might have a solution for this issue with Qt.
This is what I have right now locally in my 
KDELibs4LibraryTargets-relwithdebinfo.cmake file:

...
# Import target "KDE4__nepomuk" for configuration "RelWithDebInfo"
SET_PROPERTY(TARGET KDE4__nepomuk APPEND PROPERTY 
                                  IMPORTED_CONFIGURATIONS RELWITHDEBINFO)
SET_TARGET_PROPERTIES(KDE4__nepomuk PROPERTIES
IMPORTED_LINK_DEPENDENT_LIBRARIES_RELWITHDEBINFO "Qt4__QTCORE;Qt4__QTGUI;Qt4__QTDBUS;KDE4__kdecore"
IMPORTED_LINK_INTERFACE_LIBRARIES_RELWITHDEBINFO "KDE4__kdeui;/opt/kdesupport/lib/libsoprano.so"
    IMPORTED_LOCATION_RELWITHDEBINFO "/opt/kdelibs/lib/libnepomuk.so.4.4.0"
    IMPORTED_SONAME_RELWITHDEBINFO "libnepomuk.so.4"
  )


So, instead of the full path to e.g. QtCore.dll there is just "Qt4_QTCORE", 
which is the name of an "imported" library target for QtCore (maybe it could 
be named "Imported_Library_Qt4_QTCORE" to make clearer what it is). Where 
this points to, will be resolved at cmake-time of the application developer 
(i.e. not at kdelibs-cmake time). Still have to play a bit more with this...

Would this solve "your" issue ?
