use XDG_DATA_DIRS please

Correct me if i'm wrong but i think this program uses hard coded paths to search for themes, if so then it would be better to use paths from XDG_DATA_DIRS environmental variable because for example nix home manager uses ~/.nix-profile/share/themes to store themes and ~/.nix-profile/share/icons to store cursor themes, which this program doesn't seem to find.

We iterate over XDG_DATA_DIRS

See

labwc-tweaks/src/theme.c

Lines 172 to 177 in ae32a9f

	{ "XDG_DATA_HOME", "" },
	{ "HOME", ".local/share" },
	{ "XDG_DATA_DIRS", "" },
	{ NULL, "/usr/share" },
	{ NULL, "/usr/local/share" },
	{ NULL, "/opt/share" },

Although it looks like we don't respect : as a separator within that env var. Is that what you've got?

yep, bunch of paths separated by :
