Building bitcoin/litecoin on mac os x missing EC.h

For my own fun, I was playing around with bitcoin, to check how the parameters of the cryptocurrencies can be modified.

After recent upgrades to my OS, I could not build any longer the bitcoind. Seems like something changed on that side. Now this command

./configure --with-gui=qt5 --enable-debug
Was sistematically producing 
configure: error: OpenSSL ec header missing

EC is the file for elliptic curve cryptography. I had brew correctly configured, and the header files were all correctly present. After some time spent inspecting the issue, on github I was able to find the solution for this problem. I simply add to export the following
export LDFLAGS=-L/usr/local/opt/openssl/libexport CPPFLAGS=-I/usr/local/opt/openssl/include
There is aksi pull request on bitcoin for that, I hope I could save you some timehttps://github.com/bitcoin/bitcoin/pull/6885/files?diff=split&unchanged=expanded
