How to set up CMake to build an app for the iPhone

Question

This is closely related to my previous question, which was about using CMake to build a static library on the iPhone. I got that to work setting the CMAKE_OSX_SYSROOT<

Answer 1

For frameworks, I found this message http://www.mail-archive.com/cmake@cmake.org/msg24659.html I grabbed enough information for this:

SET(TARGETSDK iPhoneOS3.1.2.sdk)
SET(CMAKE_OSX_SYSROOT /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/${TARGETSDK})
macro(ADD_FRAMEWORK fwname appname)
    find_library(FRAMEWORK_${fwname}
        NAMES ${fwname}
        PATHS ${CMAKE_OSX_SYSROOT}/System/Library
        PATH_SUFFIXES Frameworks
        NO_DEFAULT_PATH)
    if( ${FRAMEWORK_${fwname}} STREQUAL FRAMEWORK_${fwname}-NOTFOUND)
        MESSAGE(ERROR ": Framework ${fwname} not found")
    else()
        TARGET_LINK_LIBRARIES(${appname} ${FRAMEWORK_${fwname}})
        MESSAGE(STATUS "Framework ${fwname} found at ${FRAMEWORK_${fwname}}")
    endif()
endmacro(ADD_FRAMEWORK)

Instead of setting CMAKE_EXE_LINKER_FLAGS, now I do:

ADD_FRAMEWORK(AudioToolbox MyApp)
ADD_FRAMEWORK(CoreGraphics MyApp)
ADD_FRAMEWORK(QuartzCore MyApp)
ADD_FRAMEWORK(UIKit MyApp)

This does work for OpenGLES as well.
