[CMake] Install rpath handling for iOS frameworks [solved-ish]

[Robert Bielik]

Ok, this is most certainly not the way to do it, but I added two install steps:

install(CODE "SET(FRAMEWORK_SO \"dummy.framework/dummy\")")
install(SCRIPT add_rpath.cmake COMPONENT frameworks)

add_rpath.cmake:
############
# Adds @rpath to the SO in the framework because CMake install removes it (!!!)
EXECUTE_PROCESS(
    COMMAND install_name_tool -id "@rpath/${FRAMEWORK_SO}" ${FRAMEWORK_SO}
    WORKING_DIRECTORY ${CMAKE_INSTALL_PREFIX}
)
#############

And this works with install target and packaging. But it is ugly.
