Description

When using gnome.generate_gir and specifying a list of sources to scan with sources keyword argument, there is no dependency between generated GIR XML file and those sources (unless the target happens to depend on them as well, which is very likely but not necessarily true).

Research direction
Examine the Meson gnome module implementation, specifically the `generate gir` function in `mesonbuild/gnome.py`. Look for how dependencies are tracked between the generated GIR file and the sources listed in the `sources` keyword. The issue suggests that there is no explicit dependency, so the fix would likely involve adding a dependency using `depfile` or explicitly scanning the sources. Review any existing tests for the gnome module to understand the expected behavior.
