* Update zlibng * Set cmake path more directly in zlibng to hopefully fix an issue with the build on drone * I'm dumb, missing / in path * Mackal helps with a dumb gitignore issue * Adding all the files, not sure what's ignoring them and im tired of looking * Some tweaks to zlibng build to hopefully get it to build properly. works on msvc now
