Since commit 0dd6772a89 (FindBoost: Add legacy variables and targets for
compatibility, 2019-06-14, v3.15.0-rc2~3^2~1) we query imported targets
provided by `BoostConfig.cmake` for their `IMPORTED_LOCATION_<cfg>`.
Querying this property is not allowed on INTERFACE libraries, so add a
condition to avoid doing so in case Boost adds one in the future.

Revise the wording of the warning added by commit 0dd6772a89 (FindBoost:
Add legacy variables and targets for compatibility, 2019-06-14,
v3.15.0-rc2~3^2~1) to refer to the old variables as "legacy" rather
than "standard".

Since commit 0dd6772a89 (FindBoost: Add legacy variables and targets for
compatibility, 2019-06-14, v3.15.0-rc2~3^2~1) we extract information
from imported targets provided by upstream `BoostConfig.cmake` files.
However, upstream Boost 1.71 provides some imported targets only for
compatibility. They are just INTERFACE libraries that wrap around the
real target named by `INTERFACE_LINK_LIBRARIES`. Unwrap this layer so
we can extract the real imported location.
Fixes: #19656
Running `Utilities/Scripts/BoostScanDeps.cmake` with the Boost 1.70.0
sources shows that the `timer` component no longer depends on `system`.
This is consistent with upstream Boost Timer commit `43eecbd071`.
CMake 3.12 introduced <package>_ROOT CMake and environment variables to
be valid hints to find_package(<package>). Defining Boost_ROOT is no
longer wrong if CMP0074 is set to NEW.

Remove the 1.67 upper-bound on compiler feature computation so that with
newer versions we at least get it mostly right. Leave a comment with
notes about updating features for future versions.
The Gentoo case added by commit 1673923c30 (FindBoost: Add support for
Boost 1.67 with Python version suffixes, 2018-03-18, v3.11.0~3^2) left
out the `.` version component separator and instead duplicated the RPM
case. Add the missing `.` now.
Fixes: #18743
The purpose of the `Boost::dynamic_linking` interface library is to
cause `BOOST_ALL_DYN_LINK` to be defined. Do this on all platforms
instead of just Windows.
In particular, using Boost::log trivial_logger requires to set
BOOST_ALL_NO_LIB when Boost::Log is compiled as dynamic library.
Fixes: #17813
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.
