Compile using CMake instead of Autoconf

[AnHeuermann]

Issue

The Autoconf+Make build will be removed from OpenModelica soon™, see OpenModelica/OpenModelica#14387.
At the same time we still build and test v1.26 and v1.27.

Task

• Use CMake for building and installing omc on master.

Option 1:

• Use CMake or Autoconf+Makefiles to build older versions like v1.26 and v1.27

Option 2:

• Use a Dockerfile and install older versions like a user would to

Optional:

• Use separate images for building and testing omc. Use only the installed files like a normal user would do.
