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 ...) add_subdirectory(sub) in sub: pkg_search_module(GooCanvas REQUIRED IMPORTED_TARGET goocanvas) target_sources(osm2go_lib PRIVATE src/platforms/gtk/canvas_goocanvas.cpp ) target_link_libraries(osm2go_lib PRIVATE PkgConfig::GooCanvas) Breaks: CMake Error at CMakeLists.txt:43 (add_library): Target "osm2go_lib" links to target "PkgConfig::GooCanvas" but the target was not found. Perhaps a find_package() call is missing for an IMPORTED target, or an ALIAS target is missing? Is this intended to work? There is an easy workaround, but it feels nasty: add_library(osm2go_x_lib INTERFACE) target_link_libraries(osm2go_x_lib INTERFACE PkgConfig::GooCanvas) target_link_libraries(osm2go_lib PRIVATE osm2go_x_lib)
