I've attached a test project that reproduces this issue. At the root "test"
directory, create a new directory called 'build'. So you will have
"test/build".

cd into test/build and run:

cmake -G "Xcode" ..

This will generate an xcode project for you. Open that, and right click on
main.cpp (which should be colored red because it is an invalid path) and
click "Get Info". Look at the path. It's totally wrong.
