Status
------

This change has been marked as submitted.


Review request for KDE Frameworks.


Repository: kdelibs


Description
-------

Link kde4support privately to QtX11Extras, QtSvg and QtTest

Otherwise every user of the target KF5::KDE4Support will also have
Qt5::X11Extras Qt5::Svg Qt5::Test linked.

This can cause linker errors like "ld: cannot find -lQt5::Test"

Testing
-------

I previously got the following error compiling okteta, now it works:
/usr/lib64/gcc/x86_64-suse-linux/4.7/../../../../x86_64-suse-linux/bin/ld: cannot find -lQt5::X11Extras
/usr/lib64/gcc/x86_64-suse-linux/4.7/../../../../x86_64-suse-linux/bin/ld: cannot find -lQt5::Svg

QtX11Info and QtSvg are not used in any installed headers, so IMO this should be fine
qtest_kde.h does actually include QtTest headers, but only uses these types inside macros. And I guess any user of that header already also links to QtTest


Thanks,

Alexander Richardson
