installed libusb-1.0-0-dev libhidapi-dev librtmidi-dev
and did a git submodule install

pi@raspberrypi:~/cabl/build $ cmake ..

check where rtmidi was installed.

If include files are in /usr/include/rtmidi, I had the same problem on ubuntu and I fixed it in commit f9564bb

[mstaack]

@quasart- weird.. i tried the develop branch..will recheck later

[quasart]

maybe it was installed in a different place on your distribution then

I had the same issue which led me here. Updating to the develop branch solved my problem.
