Appropriate location for cmake support files

[Mario Ceresa]

Hi all,
does anybody know where should I put cmake support files such as:

OpenIGTLinkBuildSettings.cmake
OpenIGTLinkConfig.cmake
UseOpenIGTLink.cmake

in order for cmake to find them automatically? Can I put them in
/usr/share/cmake/Modules/ ?

I read a lot of tutorials on how cmake's find_package works, but I'm
still a bit confused... Maybe there is a packaging guideline somewhere
and I missed it?

Thanks and regards,

Mario
