Compiling OPAL using OPAL package

In the past it was possible to build OPAL using the OPAL package downloaded from the wiki (then it was still on trac not gitlab). Furthermore there was a description on the wiki how this can be done.

Currently I face the problem that I'd like to build OPAL on the servers of Helmholtz-Zentrum Berlin. They use a version of a Linux distro that is outdated (several years old). Modules that provide newer versions such as at PSI are, as far as I know, not supported. That means I would have to build a lot of tools (gcc, cmake, openmpi and possibly many more) before I could build OPAL.

With the current package, OPAL-1.6.1-3, building OPAL isn't supported. Among others cmake and mpicxx/mpicc are missing.

I would propose to reenable this feature since it lowers the barrier to build and develop OPAL. This applies especially to those that aren't yet used to build software from source.
