How to run conan given a pmm-managed repo?

[david-bakin]

I'm trying to get the pitchfork repo to build. It is using conan. Apparentliy it's conanfile.py is way out of date. I don't understand conan yet, but I see the following error and:

• I don't know how to run conan though it says "you may need to run conan manually (from the build directory)". No conan is found anywhere (i.e., using which). (or Conan)
  • For example, I'd like to add a remote using conan remote add bincrafters https://api.bintray.com/conan/bincrafters/public-conan
