i would like port this engine to FreeBSD but I have problem with zlib:

Hi @Martinfx, thanks for your interest in porting the project to FreeBSD.

FreeBSD is platform not supported currently. If this is something you want to look into adding support for, it'd be greatly appreciated. A PR fixing this will be accepted. 👍
