# 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/.
