CMake: Wrong path to target executable, can't be fixed by user

Also tested with 4.6.0-rc1 (4.5.83)

When opening existing CMake project QtCreator automatically creates Run configurations for all targets. They are correct. However, when adding more targets (add_executable) to CMakeLists, it is not possible to create Run Configurations, because QtCreator automatically creates invalid path to executable, and does not allow user to change it.

For example on screenshot.
Clion automatically sets Executable to "test_virtual_ports2".
But should set to "/path/to/cmake-build-dir/test_virtual_ports2"

When trying to run I got:
""Starting test_virtual_ports2...
Executable test_virtual_ports2 does not exist.""
