[CMake] Object library doesn't work with CMake 2.8.10.2 Xcode generator

[Bin Chen]

Following CMakeLists.txt doesn't work with Xcode (4.5.2). Is there anyone experienced the same? Thanks!
Visual Studio 10 and Linux makefile works fine.

cmake_minimum_required ( VERSION 2.8.8 )

project( test )

add_library( a_obj OBJECT t1.c t2.c )
add_library( b_obj OBJECT t3.c t4.c )

add_library( a $<TARGET_OBJECTS:a_obj> )
add_library( b $<TARGET_OBJECTS:b_obj> )

add_executable( t t.c )
target_link_libraries( t a b )


::::::::::::::
t.c
::::::::::::::
#include <stdio.h>

int func1( int a );
int func2( int a );
int func3( int a );
int func4( int a );

int main()
{
    int a = 100;
    printf( "%d %d %d %d %d\n", a, func1(a), func2(a), func3(a), func4(a) );
    return 0;
}
::::::::::::::
t1.c
::::::::::::::
int func1( int a )
{
    return a*1;
}
::::::::::::::
t2.c
::::::::::::::
int func2( int a )
{
    return a*2;
}
::::::::::::::
t3.c
::::::::::::::
int func3( int a )
{
    return a*3;
}
::::::::::::::
t4.c
::::::::::::::
int func4( int a )
{
    return a*4;
}

Best regards,
Bin Chen
