And this works for both `add_subdirectory` build and standalone builds.

Provided that the user has installed BCM, I presume? Because otherwise > find_package(BCM) won't work.

Yes, of course, and considering that building standalone requires quite a bit of dependencies(six just for system) to be installed already, I don’t think one more dependency will be a problem in this scenario.

It's not a problem for standalone builds, where you do need to install and build dependencies, whether six or seven. For the add_subdirectory case, however, it changes the number of dependencies requiring installation from 0 to 1.

No, you just do `include` instead of `add_subdirectory`, but it doesn’t require installation. And in fact, in the case of doing `add_subdirectory(boost)` its completely transparent.
