>From the Boost root:

mkdir __build
cd __build
cmake -DBOOST_ENABLE_CMAKE=1 -DBOOST_INCLUDE_LIBRARIES=preprocessor -DBUILD_TESTING=ON ..
cmake --build .
ctest --output-on-failure

If on Windows,

ctest --output-on-failure -C Debug

(or Release.)

For Preprocessor, the `cmake --build .` line won't do anything, but it's
needed for other libraries.
