@LarsGit223 not sure, Geany shouldn't be looking for plugins in `$(libdir)` directly, and that's where the library should end up (tha'ts what the `lib_LTLIBRARIES` change in my PR does). If the library is getting installed into where Geany looks for plugins (ex. `/usr/local/lib/geany`) then that needs to be fixed. Are you sure you didn't accidentally install the library into the plugin directory, like when messing around with the build system?
