Hi,
I had some free time and managed to put together a working build already.
It has been tested on High Sierra (10.13.6) but should work on older versions of macOS too. Theoretically, it should work from macOS 10.10 upwards because the build is done with Xcode6.4.
My static build includes all the "delegates" that the official build offers, these are: bzlib, freetype, jng, jpeg, lcms, png, raw, tiff, webp, xml and zlib.
If needed, some libraries can be excluded in order to reduce the size of magick, which, at this moment, is of 10MB.
The build is currently done on Travis-CI thus saving the need to have an always clean environment.
I hope to hear from you soon, even for clarifications that you might need or corrections on assumptions that I might have gotten wrong.
Best regards,
Andrei Oanca
