This is a great question, I'm currently trying to answer this myself. I have an
idea that I think could work for me alas I did not yet implement it.

Setup:
Development system is connected to all test systems, I can SSH into all test
systems without giving a password using public key authentication; this could
differ for your setup, the point is that you can execute a command from your
development system on the remote system without interaction like
giving a password

Process:
1) cross-compile tests on development system
2) move tests to test systems (I mount some folders and just move binaries)
3) register tests (one for each binary and test system) with CMAKE using the
add_test(NAME <name> COMMAND <command>) syntax; the command for me would be
something like "ssh testbox1 /path/to/tests/name"

Now if you do make test, CMAKE should run all tests including the remote ones.
