# Qt and LinguistTools are used by both subprojects, so they are looked up at

# library links against it directly, PUBLIC propagation from the library
# target makes the dependency available to qwfassoc-standalone as well.
# wfassoc ships a standard config-mode package (wfassocConfig.cmake); point
# CMAKE_PREFIX_PATH or wfassoc_ROOT at its install prefix to locate it.
# toml11 is only needed when the standalone executable is built, so it is
# looked up conditionally below.
