[openssl-dev] Add a new algorithm in "crypto" dir, how to add the source code into the build system

How are the OIDs not necessary?  What about the NIDs?

I've been working on an engine to add support for SIDH, using GOST as a  
template:

   https://github.com/xoloki/openssl-sidh/

GOST already had NID support in the base openssl.  I had to add at least  
one line to crypto/objects/objects.txt to get my NID:

+# NIDs for SIDH
+1 3 102 100                 : SIDH         : Supersingular isogeny  
Diffie–Hellman

Is there some way to add the NID dynamically?  If not, how can an  
algorithm be added?  The build system in 1.1.0 at least makes this  
relatively simple.  In 1.0.x it is far more difficult.

cheers,
