Please have a look.

Overall it looks good.

Perhaps a small script (in the code base and reference it here):

* Configure your project build as normal
* Run `mkdir -p .cmake/api/v1/query && touch .cmake/api/v1/query/codemodel-v2` in the root of the cmake build tree (usually the `build` folder)
* `cmake .` to reconfigure cmake

PS: Do we need the project to be built before we start working?

[Have a look at the shell script](https://github.com/PointCloudLibrary/clang-bind/blob/7bdcbcdf3d7bbc9ad706a5184d634f4524d29428/init_bindings.sh#L19-L21).

Do we need the project to be built before we start working?

Yes. We need both cmake-file-api and compilation db.

I meant: do we need to build PCL before starting with PCL bindings or just PCL's CMake configured?

Roughly LGTM. Will merge once you're happy @divmadan
