FindKDE4
--------
Find KDE4 and provide all necessary variables and macros to compile
software for it. It looks for KDE 4 in the following directories in
the given order:
::
CMAKE_INSTALL_PREFIX
KDEDIRS
/opt/kde4
Please look in FindKDE4Internal.cmake and KDE4Macros.cmake for more
information. They are installed with the KDE 4 libraries in
$KDEDIRS/share/apps/cmake/modules/.
