Re: [boost] Request for a "Policy Review" regarding 'CMakeLists.txt'

Ok, you could just do `cmake libs/hana` for the cmake step. However, this won't build hana's dependencies. Another way would be for hana to provide a target just for its test, so using `hana-check` instead of `check`:

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

This looks like an interesting option. Is it possible to write a top-level CMakeLists.txt which would add_subdirectory for each present library in libs/ ? (b2 does this - invoking it at top level automatically works on a subset and builds whatever is present.)
