I also encountered the same problem. In the master branch or 3.4 branch or 2.4 branch. But after installing cmake, it will be fine.

In the 2.4 branch error message will show :

/bin/sh: cmake: command not found

If someone in the future will have the same problem. This problem was in the master branch, downloading branch 2.4 and adding CMake at PATH the build process go well
