Hi,
thanks for your feedback!
I will try to solve it this way:
if (CMAKE) {
build hama_pipes module
} else {
skip hama_pipes module
notify user, why hama_pipes was skipped
}
By the way, did you also observe this build failure mentioned by Chia-Hung

Just notice that <unistd.h> is not included in HamaPipes.cc. Adding
