Looking at the error message, it seems that the tests are just not enabled on your machine inside of cmake files. Probably cmake queries identity of your machine in some way (e.g. uname -a), and then fails to recognize it as power.

+Alexey for cmake magic, where does recognition of target machine happens inside of cmake files?
