Configure Error: Target "nheko" links to target "ZLIB::ZLIB" but the target was not found.

When I want to compile the current git HEAD I get this:

$ mkdir build
$ cd build
$ cmake ..

CMake Error at CMakeLists.txt:550 (add_executable):
  Target "nheko" links to target "ZLIB::ZLIB" but the target was not found.
  Perhaps a find_package() call is missing for an IMPORTED target, or an
  ALIAS target is missing?

-- Generating done
CMake Generate step failed.  Build files cannot be regenerated correctly.

I don't get the error, though. It seems that the ZLIB dependency was removed from CMakeLists.txt. The only reference that I found in the whole project is in the README (seems outdated in this respect) and one third party library. Where CMake gets this target from? (I have zlib installed, btw.)

Reverting 73e0a9f453d obviously helps.
