Looks like we still need parts of the hack, really because of the fact that secp256k1 is "special", because we are building a folder within webthree-helper, rather than running CMake on the root of a repo.   That means we are missing containing CMake elements, so we have to fake them in.    Very ugly.   They drag in a bunch of dependencies too, seemingly because the CMake files within webthree-helper are not standalone.
