# usage:
#	- create a directory
#	- place your sources and CMakeLists.txt inside
#	- insert this line in your CMakeLists.txt
#		include(${CGoGN_ROOT_DIR}/build/apps_cmake.txt)
# 	  just after defining CGoGN_ROOT_DIR
# 
# Example:
# ========
#	cmake_minimum_required(VERSION 2.8)
#	project(Pipo)
#
#	set(CGoGN_ROOT_DIR ${CMAKE_SOURCE_DIR}/../../CGoGN CACHE STRING "CGoGN root dir")
#	include(${CGoGN_ROOT_DIR}/apps_cmake.txt)

#	include_directories( ${CMAKE_CURRENT_SOURCE_DIR} ${CMAKE_CURRENT_BINARY_DIR} )
#	qt_wrap_ui( pipo_ui pipo.ui )
#	qt_wrap_cpp( pipo_moc pipo.h )
#	add_executable( pipo pipo.cpp ${pipo_ui} ${pipo_moc} )
#	target_link_libraries( pipo ${CGoGN_LIBS}  ${CGoGN_EXT_LIBS} )
#	qt_use_cgogn_modules(pipo)
#
#	WARNING: to avoid problem of DLL loading, on windows executable are generated in CGoGN/bin/....
#	Take care while choosing executable names
