upgrade cmake

Good Afternoon,

The version of cmake in the official Ubuntu 18.04 repositories is quite old, 3.10.  Given the speed at which nvidia is moving lately with CUDA, the ability of older versions (i.e. pre 3.14) of cmake3 to find CUDA-related libraries has diminished[1].  This is likely the case for other software.

While the vendor of cmake maintains an APT repository with the latest version of cmake for x86-64[2], they do not for ppc64le (and likely other architectures supported by Ubuntu).  Given Red Hat Enterprise Linux is moving towards using the latest stable version of cmake in their repositories[3], is it possible that Ubuntu can do the same or at least upgrade Ubuntu 18.04 to 3.14 (which is the latest version of cmake I've found that builds with the versions of dependency packages available in the default repositories)?  It would appear that cmake maintains compatibility within the 3.x range quite well.

Thanks
