#
# The following are defined by this module:
#  ClanLib_FOUND - TRUE if ClanLib was found
#  ClanLib_INCLUDE_DIRS - Directory containing the ClanLib headers
#  ClanLib_LIBRARIES - If invoked via FIND_PACKAGE(ClanLib COMPONENTS ...),
#                      will only contain the libraries matching each component.
#                      otherwise, it will contain all ClanLib libraries found.
# For the components Core, App, Display, GL, GUI, GUIStyleSilver, MikMod,
# Network, SDL, Signals, Sound and Vorbis, the following variables are set:
#  ClanLib_${COMPONENT}_LIBRARY - Full path to the component's library.
