[CMake] OS X, SDL, Frameworks and Libraries

[Francisco Requena]

As on my previous my post, I got a bundle with SDL.framework embeeded.
On OS X, you can either use .framework and .dylib binaries. So, I got to use
the BundleUtilities macro.

If CMake doesn't find the .framework, all works ok: I get 3 libraries
(libSDL..) on Content/MacOS folder.
If CMake finds the .framework, it just doesn't know (or it seems) how to
handle it. What can I do?

Here's the CMakeLists.txt:

cmake_minimum_required(VERSION 2.8)

project(openvolt)

set(APP_NAME OpenVolt)

include(FindSDL)
include(FindOpenGL)

include_directories(${SDL_INCLUDE_DIR})

add_executable(${APP_NAME} MACOSX_BUNDLE main.cpp)

target_link_libraries(${APP_NAME} ${SDL_LIBRARY} ${OPENGL_LIBRARIES})

string(REPLACE "-framework Cocoa" "" DIRS ${SDL_LIBRARY})
install(CODE "
  include(BundleUtilities)
  fixup_bundle(\"${openvolt_BINARY_DIR}/${APP_NAME}.app\" \"\" \"${DIRS}\")
" COMPONENT Runtime)


And here's the output when I do 'make install':
