# 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/.
