How to shorten the initial install time?

Please let us hear what you think about it!

Problem

Currently initial install of BitcoinKit takes more than 10 mins on both Carthage and CocoaPods. Mainly reason is that sh setup/build_libraries.sh takes more than 10 mins. It downloads and builds OpenSSL (libcrypto) and secp256k1.

Also, for some users, the build fails because of the lack of some dependencies like automake or libtool.

Describe what you've considered?

1. Allow binary install. [convenient but not secure as build by users]
2. Push OpenSSL and secp256k1 built files to Github.
3. Upload binary for Carthage [users can choose binary install or self compile]
4. Upload binary to CocoaPods [users can only install binary via CocoaPods]
5. Do nothing

Also the first time of carthage update always fails.

I have to add that binary install is convenient but not secure as build by users.

I don't think build time can be improved. At best, the openssl archive can be stored in the github repo instead of downloading directly from openssl.org, but download time is not that significant.

For example: https://github.com/oleganza/CoreBitcoin/blob/master/update_openssl.sh

Any updates here? I'm having a lot of problems trying to integrate BitCoinKit into my project with both Pods and Cart
