# Qt cross module dependency information within the Qt respository is wrong and/or incomplete.
# Always check the toplevel CMakeLists.txt for the find_package call and search for linkage against the Qt:: targets
# Often enough certain (bigger) dependencies are only used to build examples and/or tests.
# As such getting the correct dependency information relevant for vcpkg requires a manual search/check
