WIP: Add cmake scripts

[zbeekman]

Hi Salvatore!

Here is a pull request to start the discussion regarding integrating a CMake build system into PSBLAS3.

Changes made:

• [X] Renamed base/modules/{aux => auxil} for Windoze support (Really windows? I can't name a directory aux?!?!?! FFS)
• [X] Added CMake build scripts
• [X] Compile static or shared libraries based on whether -DBUILD_SHARED_LIBS is passed to CMake (CMake canonical convention)
• [X] Publicize build directory so that other packages can just do find_package(psblas) and get compiled targets in the build directory

Outstanding work:

• [ ] Build all possible tests. Only the hello and pingpong tests are currently built. I/we need some guidance on how and when to build the other tests
• [ ] C bindings are not currently being built
• [ ] FC and CC still need to be set to the MPI compiler wrappers because we haven't fully implemented the use of CMake's FindMPI module.
• [ ] Install things to the same end location as the Autotools build
• [ ] Appropriate system introspection is missing

Hi @zbeekman I am back in Cranfield on Friday, will take a deeper look then. Development is not active right now, so it should not be a problem. We need to have a longer chat on how to handle the other tests. S.

Hi @zbeekman I have merged the template, and have tested this version with configure/make/install and building mld2p4-2 against it. I have not tested the cmake machinery, I suppose you did that?

Hi @sfilippone this is still a work in progress. I am getting close and hope to have a finished version for you to test later today. The CMake machinery appears to be working but requires a few more tweaks and changes.

@zbeekman Ok, stainding by. Actually am very busy with classes, so I won't get back to this until weekend.

@zbeekman Be aware that I made a simple change to the copyright statements, but by its nature it is a bit intrusive.

No worries, I'll update the branch.
