Mutter (sometimes) fails to build with [fatal error: meta/meta-enum-types.h: No such file or directory]

[Daniel van Vugt]

[ Impact ]

Mutter failed to build, only once, on jammy amd64:

In file included from ../src/backends/meta-backend-private.h:39,
                 from ../src/backends/x11/meta-backend-x11.h:31,
                 from ../src/backends/x11/nested/meta-backend-x11-nested.h:25,
                 from ../src/tests/meta-backend-test.h:23,
                 from ../src/tests/meta-backend-test.c:22:
../src/backends/meta-monitor-manager-private.h:41:10: fatal error: meta/meta-enum-types.h: No such file or directory
   41 | #include "meta/meta-enum-types.h"
      | ^~~~~~~~~~~~~~~~~~~~~~~~
compilation terminated.

Seems like an old issue that you can hit at random in highly parallel builds. Because meta-enum-types.h is auto-generated its consumers need to declare stronger dependencies.

[ Test Plan ]

Build mutter.

[ Where problems could occur ]

More build failures or accidentally depending on meson features that don't exist in jammy.

Looks like it was fixed in 45.0:
