BTW, I wanted to try the cross-compiling myself for several montsh now, because I am curious, but did not find the time up to now.
The build-bot already cross-compiles for Windows, it is NOT a Windows machine. Recently travis updated their bots to to Ubuntu LTS 14.04 und I changed the scripts to use mingw-w64 shipped by Ubuntu. So when you clone https://github.com/syntheticpp/lyx.git and checkout the branch 'bleeding-edge-master', install mingw-w64 (have a look at .travis.yml) then a simple call of ./development/cmake/scripts/travis.sh starts the cross-compliation of lyx. (It does not work on Ubuntu 15.04.)
