Probably what you should be doing is to have all the general cmake
setup stuff (general sources, binary locations) setup in your top
level CMake file. Then you will have Apple.cmake (note the extension..
) and in there you start listing all your apple specific compiler
options and other options. In those platform specifc files you also
define a variable PLATFORM_SRCS that would have your list of platform
specific sources in it. In your Main CMakeLists.txt file you then do:
SET (SRCS foo.cpp)
IF (APPLE)
INCLUDE (Apple.cmake)
ENDIF(APPLE)
IF (WIN32)
INCLUDE (Win32.cmake)
ENDIF(WIN32)
SET (SRCS ${SRCS} ${PLATFORM_SRCS} )
ADD_LIBRARY (foo SHARED ${SRCS} )
The gets rid of all the extra directories. Does this help?
