I've reproduced the error. A possible fix would be to extend
pkg_check_module and pkg_search_module to allow globally imported
targets, i.e. to add an IMPORTED_GLOBAL_TARGET or GLOBAL keyword (where
the latter is only usable together with IMPORTED_TARGET) to allow
similar control as
It seems that CMake does not find PkgConfig::GooCanvas because it is

I played a bit around with that as I hope it would simplify some things in
OSM2go, but it looks there are still some limitations:
in main:
add_library(osm2go_lib ...)
