zlib-ng
Compiles zlib-ng as a static library, which is later included by
pythoncore.vcxproj. This was generated using CMake against zlib-ng
version 2.2.4, and should be minimally updated as needed to adapt
version 2.2.5, and should be minimally updated as needed to adapt
to changes in their source layout. The zbuild.h, zconf.h and
zconf-ng.h file in the PC directory were likewise generated and
vendored.
