believe it's a few months old, I just decided to use that one since it
already had all the stuff inplace for android (the guy that made the repo
copied all the google changes to make it compatible with android's build)
but even compiling it from source is not an issue.. And I agree that this a
static build is the way to go.

Please share your thoughts, I was more interested in the how rather than
the if in this question :)
How do I disable OpenSSL engine support in curl and still be able to make
https calls?
