Since commit v3.13.0~7^2 (FindBoost: Improve compiler prefix
detection for GCC 5+ and clang 4+, 2018-11-07) we run the internal
`_Boost_COMPILER_DUMPVERSION` macro on all UNIX platforms. Teach
the macro to tolerate missing `CMAKE_CXX_COMPILER_VERSION`, which
occurs when the CXX language is not enabled.
Fixes: #18624
Add recognition of compiler version and prefix for clang.
Accommodate changes to version numbering scheme for GCC 5+ and clang 4+
- Minor number becomes patch, so excluded it from compiler prefix.
- Improves searching for Boost 1.69+ libraries built with GCC 5+ and
clang 4+, where library names are generated with compiler tag based on
major version only eg. -gcc5 for GC 5.5.0 or -clang6 for clang 6.0.0
- Follows up related changes in upcoming Boost 1.69
https://github.com/boostorg/build/pull/349
Dump detected compiler version in Boost_DEBUG message.
Replace use of CMAKE_COMPILER_IS_GNUCXX with CMAKE_CXX_COMPILER_ID.
Add the system thread library to Boost_LIBRARIES when the boost thread
component has been found.
The Boost::thread imported target already pulls in Threads::Threads.
This changes does the same for projects using the Boost_LIBRARIES variable
instead.
Boost 1.66 and above built with `--layout=versioned` add an architecture
tag to the library file names. We already try to compute this tag
automatically when `CMAKE_CXX_COMPILER_ARCHITECTURE_ID` is available,
but that is currently not computed everywhere. Add an explicit
`Boost_ARCHITECTURE` option that a user can set to specify the
architecture tag.
Issue: #17701
Search paths for boost versions should be build using _boost_TEST_VERSIONS
instead of _Boost_KNOWN_VERSIONS because if Boost_FIND_VERSION_EXACT
is used _Boost_KNOWN_VERSIONS is empty and boost isn't found even in its
default installation path.

Update `mpi_python##` and `numpy##` component dependencies to honor
python version suffixes on components named by the caller. Although
upstream Boost did not add version suffixes prior to version 1.67, it is
commonly done by distros. Honor suffixes specified by project code.
Projects must take responsibility for naming distro-specific component
suffixes for versions prior to 1.67.
Fixes: #17892, #17970
Per discussion on cmake/cmake#17575, this protection not particularly
valuable, as the dependency information which the imported targets wrap
is generated anyway.
This removes a road-block for using `Boost_ADDITIONAL_VERSIONS` to
support newly-released Boost versions pending a new CMake release.
Release notes: http://www.boost.org/users/history/version_1_66_0.html
* All new libraries are header-only.
* _Boost_COMPONENT_DEPENDENCIES is unchanged from 1.65.1
* _Boost_FIBER_COMPILER_FEATURES is unchanged from 1.64.0
