According to error log, you didn't install ninja build system. sudo apt-get install ninja-build

I should also point out that ubuntu has two things called ninja, you want the 'ninja-build' package, not the 'ninja' (eg the /usr/sbin version).

You probably have to deinstall the ninja package.

There are directions in README.md you need to follow:

$ apt-get install build-essential cmake gcc libnl-3-dev libnl-route-3-dev ninja-build pkg-config valgrind
