This is an example project showing the usage of cmake's find_package(). There are four projects:
- foo: a simple library
- foo_user: an executable using library foo
- bar: a simple library using foo
- bar_user: an executable using library bar
In essence, bar_user has a transitive dependency to library foo via library bar.
It looks that cmake's install(EXPORT ...) commands don't emit statements to
handle transitive dependencies out-of-the-box.
Therefore, we let install(EXPORT ...) generate a "private" config file and install
a self-written "public" config file which handles the transitive dependency.
Please have a look into bar/CMakeLists.txt and bar/barConfig.cmake
