If your build system generate an opam .install file, you can install files at an arbitrary absolute path on the system by specifiying a path in the `misc:` section (see section 2.2.3 of the opam developer manual).  

During install opam will then prompt the user if it allows to install the file at the given absolute path. I don't think this has been used much (if ever) so I don't know if it will ask you to sudo if it detects that it has not the privileges to install there (but I highly suspect the answer is no).

Best,
