That happens when some required dependencies are not listed.  If I use the
current recipe in meta-soletta it works fine, but if I revert the last
commit (that adds inherit pkgconfig) then it fails just like that.  So, my
expectation is that you're using an old clone of meta-soletta and need to
pull the latest version (or if you can't do that, add pkgconfig to the
inherit list in that recipe).
