Depends: cmake but it is not going to be installed

Asked by Gichan Jang

I failed to build the nnstreamer-edge package due to unmet dependency problem.
I passed for 20.04(amd64, arm64, armhf) and 18.04 (amd64) but failed 18.04 (arm64, armhf)
nnstreamer-edge package requre minimum cmake 2.7 (CMAKE_MINIMUM_REQUIRED(VERSION 2.6))
As I know, launchpad ubuntu provides cmake 3.10.
So, I don't know why the problem has been happened.
Please give me some hint. Thanks.

It seems that for the amd64 version (working) cmake is installed from PPA:aroth/ppa and for the armhf and arm64 version (not working) it is attempted from PPA:ecal/cmake-3.13. Both are not the standard Ubuntu repositories.

Thanks. I removed PPA:aroth/ppa and it works well.
