There are many libraries ready for building & testing with CMake: 
Mentioned (Atomic, Filesystem, Log, JSON), Mine (Nowide, Locale) and 
likely all Peter is maintaining.

Useful Information are in the Readme at https://github.com/boostorg/cmake


Examples in each library CI configs and the templates of Boost.CI: 
https://github.com/boostorg/boost-ci/blob/master/.github/workflows/ci.yml


To get you started:

cd $BOOST_ROOT
mkdir build_cmake && cd build_cmake
variant=Debug # Or Relase, or RelWithDebInfo
cmake -DCMAKE_BUILD_TYPE=$variant 
-DBOOST_INCLUDE_LIBRARIES='locale;atomic;log;time' 
-DBUILD_SHARED_LIBS=ON -DBUILD_TESTING=ON -DBoost_VERBOSE=ON ..
cmake --build . --target tests --config $variant -j 16
ctest --output-on-failure --no-tests=error -C $variant -j 16

- BUILD_SHARED_LIBS can be ON or OFF for shared or static libraries
- On Linux $variant typically only needs to be in the first `cmake` 
invocation, but it doesn't hurt in the others
- Convenience targets "tests" and "check" exists (build command) to 
build all tests (& dependencies) and run them ("check" target)
