[PATCH v2 0/3] cmake: fix autogenerated clar headers

Hi,

this is the second version of this patch series that fixes building clar with the CMake build system.

Changes compared to v1:

  - Use a for loop instead of `while; shift`.

  - Provide a bit more context around the PRIVATE/PUBLIC switch in the
    commit message.

Thanks!

Patrick

    +    Fix this by including the binary directory instead of the source
