Something like this:

git clone git@github.com:boostorg/hana.git mkdir build && cd build cmake ../hana/ cmake --build . cmake --build . --target check cmake --build . --target install

This builds, tests, and installs hana.

I wonder how this workflow would look like if we assume Boost layout, > f.ex. from an extracted release tarball.

It should be the same., if boost supports cmake. So, boost should provide a top-level cmake that calls add_subdirectory for each library that has a CMakeLists.txt file. However, this can be done later.

You're talking about building the whole Boost, and that's not what I meant. I asked about the equivalent of the above, building, testing and installing Hana, but from the directory structure of a Boost distribution.

Boost is a monolithic release, it might indeed be good to think about how the outcome of the CMake discussion interacts with the other profound change that has been worked on not so long ago: to model and reduce dependencies between libraries and break the monolithic structure.
