${PLATFORM_DEFINES} )
string( REPLACE ";" " " PLATFORM_DEFINES_ARG "${PLATFORM_DEFINES}" )
ExternalProject_Add( target
....
CMAKE_ARGS -DPLATFORM_DEFINES=${PLATFORM_DEFINES_ARG}
......
)
and in the target cmakelists to use the argument
STRING( REPLACE " " ";" PLATFORM_DEFINES ${PLATFORM_DEFINES} )
add_definitions( ${PLATFORM_DEFINES} )
