Good, it is much more modern and more powerful.

The myproj-targets.cmake file that install(EXPORT) puts in the
install tree should already have all the dependencies (actually
that file includes a per-configuration file which defines all
the libraries).  See this page for details:

What are you putting in the Config?  Typically the <pkg>Config.cmake
file should just include the file produced by install(EXPORT).
