描述

When running meson build on a a system without the libgirepository1.0-dev package installed, I got this very cryptic error:

Program g-ir-scanner found: YES (/usr/bin/g-ir-scanner)
Program g-ir-compiler found: YES (/usr/bin/g-ir-compiler)
Meson encountered an error in file subprojects/gstreamer/gst/meson.build, line 270, column 4:
gobject-introspection dependency was not found, gir cannot be generated.

I'd expect to have the error I found in the meson logs show up in the main config:

Determining dependency 'gobject-introspection-1.0' with pkg-config executable '/usr/bin/pkg-config'

研究方向
Investigate Meson's gnome module (likely in mesonbuild/gnome.py) to understand how the dependency for gobject introspection 1.0 is resolved. The issue occurs when pkg config fails to find the .pc file, but the error is not propagated correctly. Look at the code around line 270 in subprojects/gstreamer/gst/meson.build? Actually the error location is in Meson's own code. The fix should ensure that when the dependency is not found, a clear error message is displayed instead of a generic one. Check if there are any existing PRs or comments on this issue.
