Summary0015194: Xcode projects fail with only object files
DescriptionGenerated project Xcode fails to build libraries with only object input files. Test repo:

https://github.com/stopiccot/cmake_xcode_bug [^]

Xcode fails to create output file for "output_library_bugged" target nevertheless reporting that build succeeded. Everything is fine for "output_library_fixed" target. This actually maybe an Xcode not a CMake bug but we should consider adding this workaround into CMake. Example of real world project that suffers from this issue - https://github.com/PixarAnimationStudios/OpenSubdiv. [^]

This is a known limitation of Xcode and it is documented in the add_library command:

 http://www.cmake.org/cmake/help/v3.0/command/add_library.html [^]
 "Some native build systems may not like targets that have only object files, so consider adding at least one real source file to any target that references $<TARGET_OBJECTS:objlib>."
