Hi Geoffroy. This is cool work. I cannot help you in the details of how to commit that in SVN as I have no idea. Listen to David.

Now...I have a couple of ideas:

1) regardless that, it would be really really cool if you can document all this in the pharo collaborative book. As you can see there is already a chapter for VM

http://book.pharo-project.org/book/Virtual-Machine/

and the windows part is empty: http://book.pharo-project.org/book/Virtual-Machine/Building/BuildVMOnWindows/

So...we can write the two possibilities to compile in Windows: the standard one and this new one using CMake.
You can start writing the one of CMake :)
If you want, please just let us know and we create a user for you.

2) In addition, I think it would be a good idea to have a Git for scripts for the VM. If Squeak VM developers like them, they can also include it in the svn.

Laurent Laffont already has a git repository with scripts like easy_squeakvm or something like that. So, you may want to commit your code there too.

3) What about integrating like easy_squeakvm  with this ?  or do a easy_squeakvm  version of CMake for winwows ?  I would love to do for example:

./easy_squeakvm.sh --os=Windows  or ./easy_squeakvm.sh --os=Unix  

4) Would be  really great to have a Screencast about how to compile windows with CMake :)

Cheers and continue pushing.
