# FindCEGUI
#
# Locate CEGUI LIBRARIES
#
# This module defines
#    CEGUI_FOUND, if false, do not try to link to CEGUI
#    CEGUI_INCLUDE_DIR, where to find headers.
#    CEGUI_LIBRARIES, the LIBRARIES to link against
#    CEGUI_BINARY_REL - location of the main CEGUI binary (win32 non-static only, release)
#    CEGUI_BINARY_DBG - location of the main CEGUI binaries (win32 non-static only, debug)
#
#
#         Modules :
#    CEGUI_${COMPONENT}_FOUND - ${COMPONENT} is available
#    CEGUI_${COMPONENT}_INCLUDE_DIRS - additional include directories for ${COMPONENT}
#    CEGUI_${COMPONENT}_LIBRARIES - link these to use ${COMPONENT}
#    CEGUI_${COMPONENT}_BINARY_REL - location of the component binary (win32 non-static only, release)
#    CEGUI_${COMPONENT}_BINARY_DBG - location of the component binary (win32 non-static only, debug)

# People have asked us to include a FindCEGUI that is high quality that they will
# be able to copy and use to find CEGUI, so we have finally done that.
