[PATCH] Fix CMake return check for export tests

[Scott Kostyshak]

The CMake export tests would never fail because the return status was
not checked correctly. The attached patch fixes this.

I guess that CMake is similar to bash in that it does not throw an
error when using an undefined variable? Is there any way to ask it to?

Can the patch go in?

Thanks, Scott
