I do not enable `rapidcheck` tests. At least in theory enabling tests
via `-DRC_ENABLE_TESTS=ON` should be enough. In practice
`ext/CMakeLists.txt` implies a certain layout of `check2`, `gtest` and
`boost` dependencies checked out locally:

  git submodule:

    if (RC_ENABLE_TESTS OR RC_ENABLE_CATCH)
      add_subdirectory(catch)
    endif()

  another git submodule:

    if ((RC_ENABLE_GMOCK OR RC_ENABLE_GTEST) AND RC_ENABLE_TESTS)
      # On Windows, gmock/gtest defaults to static CRT which is not compatible
      # with the way RapidCheck is currently built
      set(gtest_force_shared_crt ON CACHE BOOL "" FORCE)
      add_subdirectory(googletest)
    endif()

  ad-hoc checkout with a stand alone script:

    if (RC_ENABLE_BOOST AND RC_ENABLE_TESTS)
      if (NOT EXISTS "${CMAKE_CURRENT_LIST_DIR}/boost")
        execute_process(
          COMMAND "sh" "get_boost.sh"
          WORKING_DIRECTORY "${CMAKE_CURRENT_LIST_DIR}")
      endif()
      add_library(boost INTERFACE)
      target_include_directories(boost INTERFACE boost)
    endif()

I did not try to satisfy these requirements. Ideally upstream should be
fixed to use already installed libraries. But I'm not very well versed
in `cmake` to propose such a change just yet.
