Geany plugins now build if configured --prefix=/home/lex/geany_meson --with-geany-libdir=/home/lex/geany_meson/lib and install to $PREFIX/lib/geany but do not appear in plugin manager.
You have to use the correct libdir, obviously, i.e. `--with-geany-libdir=/home/lex/geany_meson/lib/x86_64-linux-gnu`. Typically you avoid setting `--with-geany-libdir` and instead point pkg-config to the correct `geany.pc`. Under ubuntu, geany.pc has this line: `libdir=${exec_prefix}/lib/x86_64-linux-gnu`
I configure G-P like this:
`./configure PKG_CONFIG_PATH=/home/kugel/dev/geany.git/build-meson/dest/lib/pkgconfig --prefix=/home/kugel/dev/geany.git/build-meson/dest/`.
IMO, the `PKG_CONFIG_PATH` ought to be enough and the prefix should follow automatically but that's not how G-P configure works currenty
