Just gave it a quick shot, with the same tests as last time: build and install Geany, build and install G-P against the previously built Geany and compare file system differences.
The complete boring results are in https://gist.github.com/eht16/673f850caf4d4989b3c3a53b6748d754.
It looks much better now: - the differences in installed Geany files between Autotools and Meson are much smaller - G-P compiles and installs
However, there are still issues: - G-P installs into `/tmp/meson-install/lib/geany` but Geany's plugins are installed to `/tmp/meson-install/lib/x86_64-linux-gnu/geany` and Geany also looks only in its path, i.e. we still have a problem with the `x86_64-linux-gnu` part - there are still file system differences: - `share/icons/hicolor/24x24/apps/geany.png` is installed by Meson but not by Autotools, might be fine but why? - `share/doc/geany/LexillaLicense.txt` is missing with Autotools but already known and Lex created an issue for it - `share/icons/Tango/icon-theme.cache` is missing with Meson but probably harmless - Meson adds the `x86_64-linux-gnu` in LIBDIR. Might be correct and fine but G-P should notice and use it then
