Hi Sergei,
I can maintain cmake scripts.
Wow! Great! Welcome on board :) So, to get started with the thing, can you get the scripts from the history in the repo and double-check them against autotools build scripts. The goal is to ensure that all the feature macros are defined in the same way under CMake and autotools. Also, take care to generate the version numbers in the same way as autotools do. Version numbering has to be consistent otherwise it'll be a mess (imagine people reporting bugs with inconsistent version numbers). Once done, send me the patch (don't forget to mention it's MIT licensed!) and I'll merge it in. Afterwards, we can proceed to adjusting the CI environment to build both CMake and autotools versions on all platforms etc. Martin
