Summary0013452: Invalid path generated to .o files in an object library with Xcode Generator
DescriptionWhen linking an executable to a library built using the new object library format for add_library(), the path to the .o files is invalid when linking the final executable.

I've attached a sample project:

CMakeLists.txt - project(CMAKE-BUG)
|
| - liba/CMakeLists.txt - project(A)
|
| - exec1/CMakeLists.txt - project(exec1)
|
| - exec2/CMakeLists.txt - project(exec2)

When Xcode goes to link the .o file from liba, the path given to the linker is:

/Users/grant/Development/CMakeBug/build/liba/exec2.build/Debug/A.build/Objects-normal/x86_64/a.o'

However, the actual path to the .o file is:

clang: error: no such file or directory: '/Users/grant/Development/CMakeBug/build/liba/CMAKE-BUG.build/Debug/A.build/Objects-normal/x86_64/a.o'

Somehow the folder that should be named CMAKE-BUG.build, after the top level project name, is being replaced with the name of the last executable project name that was loaded. In this case, exec2.build.


Steps To ReproduceSee attached minimal sample. Build on OS X with arguments "-G Xcode"
