Run the main executable created in the autogen tests.

Don't try to show the windows, which would require a gui capable test

Automatically link to qtmain.a on Windows to avoid a policy warning. Set
policy CMP0020 to NEW by increasing the required version.

Don't attempt to run the test when using Windows.
