Code review comment for lp://staging/~thomas-voss/net-cpp/fix-1423765

I just pulled the branch, ran cmake and successfully compiled it. Then, when running the tests, I got the famous "A requested feature, protocol or option was not found built-in in this libcurl due to a build-time decision." again.

net-cpp should not build if the modules it depends on are not installed. Could you please add whatever run-time dependencies there are to the build dependencies. I know we've been down this road once before, but I've forgotten what the missing packages are. And the error message that comes out of curl is singularly unhelpful. It would be sooo nice if the error message actually state *what* the thing is that couldn't be found :-(
