John W. Parent 7e8415a3a6 Windows: auto-add WGL/SDK as externals (#43752) ... Adds a pre-concretization check for the Windows SDK and WGL (Windows GL) packages as non-buildable externals. This is a redo of https://github.com/spack/spack/pull/43459, but makes sure to modify the configuration scope outside of the bootstrap scope: whichever is highest-precedence in the user's environment at the time the concretization runs, which should either be an env scope or the ~ scope. Adds pytest fixture mocking the check for WGL and WSDK as if they were present.		2024-05-02 01:05:03 -06:00
