Update the list of known versions.
Run the command
cmake -DBOOST_DIR=/path/to/boost_1_75_0 \
-P Utilities/Scripts/BoostScanDeps.cmake
to extract dependencies from the 1.75.0 source tree.
They differ from 1.74's dependencies by the addition of
dependencies of the json component, so add a new version
block to FindBoost.
Fixes: #21773
* Split large literal blocks into definitions lists.
* Add section headers.
* Add links to standard commands and variables.
* Use inline literals liberally.
* Enable code highlighting in literal blocks.
* Format command signatures according to modern conventions.
Since commit 4b2a61946f (FindBoost: Honor BOOST_ROOT when finding
upstream BoostConfig, 2020-10-22, v3.19.0-rc2~14^2) we accidentally leak
our internal setting of `Boost_ROOT`. Revise the logic to unset our
temporary value.
Fixes: #21379
When boost is built with `BZIP2_SOURCE` or `ZLIB_SOURCE` it will
generate boost versions of these libraries. Since commit cb1a434ce0
(FindBoost: Add check headers for `zlib` and `bzip2`, 2016-07-01,
v3.7.0-rc1~400^2) we look for them only on Windows where they are
commonly provided, but they may be available on every platform.
Run `Utilities/Scripts/BoostScanDeps.cmake` with the Boost 1.73.0
sources to compute dependencies.
This includes a new Boost.Nowide library.
Special case: Boost.Filesystem is an optional dependency as the include
is only required to make Boost.Filesystem use UTF-8 paths on user
request
On platforms where our default Boost static library prefix is incorrect,
make it possible for users to set it explicitly to work around the problem
until FindBoost can be updated.
Fixes: #20372
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.
Fixes#18810
