Hello,

I am currently trying to implement HTM on Ubuntu 14.04, however I am stuck on the set up portion as described in ([Compiling NuPIC on Ubuntu 14](https://discourse.numenta.org/t/compiling-nupic-on-ubuntu-14/2102)).

this line to be exact: cmake $NUPIC\_CORE -DCMAKE\_INSTALL\_PREFIX=…/release -DPY\_EXTENSIONS\_DIR=$NUPIC\_CORE/bindings/py/nupic/bindings

its saying that Cmake 3.3 or higher is required and im running 2.8.12.2 , even though ive installed cmake 3.13

not to sure how to fix this problem.

Thank you for your help.

I have not built C++ on linux in ages. But we do run it in [CI in Ubuntu](https://circleci.com/gh/numenta/nupic.core). You can see the exact commands run here:

I hope that helps.

Thank you for getting back to me.

Ill definitelly look into that. I guess what i need to do is figure out how to upgrade the cmake version from 2.8 to 3.3 or higher.

I just tried sudo apt-get upgrade but its still telling me that cmake is still 2.8
