I think its basically setting variable to include paths, defines and
libraries, that the calling CMakeLists.txt can use. I make my
*Config.cmake files look relative to their location and use an exports
file from CMake for the libraries.
======= FooConfig.cmake ===
SET(FOO_EXPORT_FILE "${Foo_DIR}/FooExport.cmake")
SET(FOO_INCLUDE_DIRS "${Foo_DIR}/../include")
INCLUDE(${FOO_EXPORT_FILE})
SET(FOO_LIBRARY foo)
# build config stuff for Foo (requires configure_file)
SET(FOO_USE_BAR @FOO_USE_BAR@)
=======
Then in the CMakeLists.txt of Foo, I put a configure_file(... @ONLY) for
the *Config.cmake file and add an
install(EXPORT Foo FILE FooConfig.cmake DESTINATION lib COMPONENT
Development)
And for the install(EXPORT ...) to work, I use the EXPORT flag in
install(TARGETS ...)
install(TARGETS foo EXPORT Foo ....)
To use
find_package(Foo)
include_directories(${FOO_INCLUDE_DIRS})
...
target_link_libraries(baz ${FOO_LIBRARY})
There may be a more official way, but that's kind of how I do them and
it works nicely.

So, there are a few of us quickly port the HDF5 1.8 code to CMake. I'm
thinking that we should put in an HDF5Config.cmake file for other
projects use. Simple question:
What goes in one of those? Is there a tutorial somewhere? Where does
the file get installed into? What does the consumer of the file need
to put into their cmake files?
And what version of CMake does all that apply to?
Thanks
