Transform simulavr project to cmake instead of automake

[Thomas K]

Hi Guys,

i've now pushed a branch to simulavr git repository to have the build 
made with cmake instead of automake tools. The branch is named 
dev-cmake. It's in the moment incomplete because the examples are not 
transformed and are in the moment in the old directory. All other should 
work, means:

- build simulavr and lib

- build tcl, python and verilog module

- create documentation

- create debian packages

The code is based on the current master HEAD!

To make it easier to handle I have added a short makefile in root 
directory to control the build process. Call 'make' without target will 
show a short help for the available targets. To build just simulavr and 
lib, you have to type: 'make no-debug' followed by 'make build'. The 
configuration targets will switch on or off the additional build components.

On word about supported platforms: it's (in the moment, even if cmake 
supports other platforms) only for linux, no support for Windows or Mac 
(I have no Mac!). Why? simulavr can run in a docker image and docker is 
available for all platforms. (as far as I know!) If we later support a 
docker image it's possible to use simulavr on all platforms but have not 
the problem to make fixes, because something will not work just on one 
platform.


Please check it, if this will work for you and let me know, if this is 
working or not to shift this to master branch later and make all further 
work on this base.


cu, Thomas
