# macro to configure the use of local or system version of a package
# Uses:
#	HAVE_LOCAL_${name} - is local version available?
#	${name}_LOCAL_LIBRARIES - libraries of the local version
#	${name}_LOCAL_INCLUDE_DIRS - include directories of the local version
#	HAVE_SYSTEM_${name} - is system version available?
#	${name}_SYSTEM_LIBRARIES - libraries of the system version
#	${name}_SYSTEM_INCLUDE_DIRS - include directories of the system version
# Generates:
#	WITH_LOCAL_${name} - use the local version of the package (only when local is available)
#	WITH_${name} - use this package
#	${name}_LIBRARIES - libraries
#	${name}_INCLUDE_DIRS - include directories
