And that is what the example is *about*. The FooBar project *exports*
its targets, along with their dependencies, so that when other projects
do find_package(FooBar), they will be able to link against the foo
library without having to know any of the dependencies of it. E.g. the
project "hello" might look like this:

project(hello)
find_package(FooBar REQUIRED)
include_directories(${FOOBAR_INCLUDE_DIRS})
add_executable(hello hello.c)
target_link_libraries(hello ${FOOBAR_LIBRARIES})
