## libsl-mini
##
## This file use the LIBSLMINI_DIR cmake variable as input to search files/dirs
##
## This file may provides:
## * LIBSLMINI_GL_HEADERS_ONLY_DIR : this is the include dir for OpenGL compatibility
## * LIBSLMINI_QT_HEADERS_ONLY_DIR : this is the include dir for Qt/GL compatibility
##
## example 1 :
## find_package(LIBSLMINI REQUIRED QT)
## if(LIBSLMINI_FOUND)
## INCLUDE_DIRECTORIES(${LIBSLMINI_QT_HEADERS_ONLY_DIR})
## endif()
##
## example 2 :
## find_package(LIBSLMINI REQUIRED GL)
## if(LIBSLMINI_FOUND)
## INCLUDE_DIRECTORIES(${LIBSLMINI_GL_HEADERS_ONLY_DIR})
## endif()
##
## example 3 :
## find_package(LIBSLMINI)
## if(LIBSLMINI_FOUND)
## INCLUDE_DIRECTORIES(${LIBSLMINI_GL_HEADERS_ONLY_DIR})
## INCLUDE_DIRECTORIES(${LIBSLMINI_QT_HEADERS_ONLY_DIR})
## endif()
##
## This file declare a LIBSLMINI_DOWNLOAD_OVERWRITE cache GUI cmake flag allowing
## to download the libsl-mini public svn project in the BINARY_DIR and set the LIBSLMINI_DIR.
## So if you want to update this project, be sur you have no modification no commited/pushed
## and use this (one shot) flag to re-download and overwrite the libsl-mini project.
##
## NOTE:
## libsl-mini LIBSLMINI_GL_HEADERS_ONLY_DIR use CImg.h internaly
## which need to use external tools like ImageMagick or GraphicMagick.
