With OMake's design, it is not possible to do real out-of-tree builds,
if you mean outside-the-project-dir. However, it is possible to to
in-tree builds with separate build directories for different build
hosts.

This seems to be inside the tree, so it should work fine.  As said in
another answer, you need to look at the vmount feature.
