On our suggestion, ITI have changed the way the API is built in the new version of the code (DX11).
In addition to this we now have it on the compute nodes.
The standard procedure for usage on any CFI machine is to now setup the environment using cadfix_setups.sh. On the compute nodes the same environment is now setup with module load cadfix.
This MR now correctly uses these environments to build NekMesh, its now very easy compared to the old method which was hell!
