That's not necessary, since CMake searches the common locations on its
own. Now, /usr/local would be common, but not /usr/local/atlas.

Set the environment variable CMAKE_PREFIX_PATH to /usr/local/atlas
before you run CMake. This tells CMake to first go look in
/usr/local/atlas, and only then consider all the other default locations.
