[CMake] Xcode generator ignores shared library made of object libraries

[Pere Mato Vila]

Hi,

  I am using cmake version 3.1.3 on MacOSX 10.10.2. I want to build a SHARED  library made exclusively of OBJECT libraries. This works well with the Makefile generator but fails with the Xcode generator.

  To reproduce the problem is very simple:
cmake_minimum_required(VERSION 2.8.8 FATAL_ERROR)

add_library(FooObjs OBJECT foo.cxx)
add_library(Foo SHARED $<TARGET_OBJECTS:FooObjs>)
add_executable(FooMain main.cxx)
target_link_libraries(FooMain Foo)


The library libFoo.dylib is never build. I can bypass the problem by adding a dummy.cxx file to the SHARED library, but I am not convinced this is the right solution.

Cheers,

Pere
