# 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
# - KDEDIR
# - /opt/kde4
# - /opt/kde
#
# Please look in FindKDE4Internal.cmake and KDE4Macros.cmake for more information.
# They are installed with the KDE 4 libraries in $KDEDIR/share/apps/cmake/modules/.
