We do something similar in pycryptopp, but instead of automatically testing for
the locally-available C library, we just ask the human to manually pass
"--disable-embedded-cryptopp" if they want it to attempt to link to a library
external to its own bundled one:

If you succeed at this, I'd like to know how you did it! Maybe we could do
something similar for pycryptopp.

I don't understand the question. This sounds like the normal thing that
distutils has always done for modules made up of compiled C code.
By the way, if I were starting pycryptopp today I would use cffi. (And I would
name it "crpyto".)
