You should use a config file, e.g. foobar-config.cmake, instead of a
find module FindFoobar.cmake; the latters are intended as third party
contributions if one hasn't control over the concerned project's code
base while the formers are delivered as part of the project. From the
user's perpective, both behave quite the same, but config files are
searched using a more sophisticated procedure than find modules.

If you stick to a find module other projects can set CMAKE_MODULE_PATH
to locate FindFoobar.cmake outside of ${CMAKE_ROOT}/Modules, but if you
provide a config file FIND_PACKAGE() in other projects' CMakeLists.txt
files looks at various convenient locations, and that should be of a
particular interest to you w.r.t. non-root installations.
