build: add options to disable part of the build

[Lorac]

Part of the build is not always useful. Make it possible only to deploy the source without testing.

We are currently using mpunit inside yocto system, and at the moment we need an extra patch to remove docs and tests. Having those options could clean up the way the recipe is built. We have to maintain a patch instead of specifying CMake options.

Do not change the current behaviour and keep the option to ON as default.

Hi,

First of all, it is great that you find this library useful in your work.
However, we do not plan to add CMake options to the build. See more in #278. I hope it helps?

Thanks for the information, we modified our yocto recipe to reflect that.

You are welcome! The main reason not to do what you proposed is that it is not only about disabling parts of the build. You really do not want to import our compilation warnings and other development environment settings as well. The CMake file in ./src is pure and does not modify your compilation environment in any way, and should be used by users. The top-level file is meant as an entry point for project development (i.e. open in the IDE).
