Since commit v3.8.0-rc1~136^2 (FindBoost: Search official location of
prebuilt binaries on Windows, 2016-12-21) we pass input paths through
`_Boost_UPDATE_WINDOWS_LIBRARY_SEARCH_DIRS_WITH_PREBUILT_PATHS` in more
places than before. This broke tolerance of backslashes in paths
provided by the user due to the macro argument re-parsing. Turn
`_Boost_UPDATE_WINDOWS_LIBRARY_SEARCH_DIRS_WITH_PREBUILT_PATHS` into a
function instead of macro to avoid re-parsing of macro arguments.
Fixes: #16816
Changes in commit 3ca6f70f (FindBoost: Allow testing for multiple
compiler suffixes, 2017-03-28) accidentally left a `set()` instead of a
`list(APPEND)` while constructing `_boost_RELEASE_NAMES`. Fix the logic
to match what was done for `_boost_DEBUG_NAMES`. Otherwise we drop some
of the candidate names.
Update the module to enable finding components of Boost 1.64 (beta) from
the upcoming release. Also update the Boost library name mangling used
for VS 2017 to match a change made to Boost upstream (vc150 => vc1410).
This fixes a regression introduced by commit v3.3.0-rc1~5^2~2
(FindBoost: Search for debug and release libraries separately,
2015-01-26). The `_Boost_CHANGE_LIBDIR` variable was split into
`_Boost_CHANGE_LIBDIR_{DEBUG,RELEASE}` but one usage site was not
updated.
Make it possible to find Boost in the default install path (`c:\boost`)
of an official prebuilt binaries installation even when `BOOST_ROOT`
has not been specified.
Per-source copyright/license notice headers that spell out copyright holder
names and years are hard to maintain and often out-of-date or plain wrong.
Precise contributor information is already maintained automatically by the
version control tool. Ultimately it is the receiver of a file who is
responsible for determining its licensing status, and per-source notices are
merely a convenience. Therefore it is simpler and more accurate for
each source to have a generic notice of the license name and references to
more detailed information on copyright holders and full license terms.
Our `Copyright.txt` file now contains a list of Contributors whose names
appeared source-level copyright notices. It also references version control
history for more precise information. Therefore we no longer need to spell
out the list of Contributors in each source file notice.
Replace CMake per-source copyright/license notice headers with a short
description of the license and links to `Copyright.txt` and online information
available from "https://cmake.org/licensing". The online URL also handles
cases of modules being copied out of our source into other projects, so we
can drop our notices about replacing links with full license text.
Run the `Utilities/Scripts/filter-notices.bash` script to perform the majority
of the replacements mechanically. Manually fix up shebang lines and trailing
newlines in a few files. Manually update the notices in a few files that the
script does not handle.
The official Windows builds of Boost have internal implementations for
`zlib` and `bzip2` libraries used by Boost::iostreams library, e.g.
* boost_bzip2-vc140-mt-1_59.lib
* boost_zlib-vc140-mt-1_59.lib
Add check headers for these so that users can specify them as
components without any warnings.

FindBoost only detects Debug and Release configurations. All other
configurations will fall back to the configuration listed as the first
entry in `IMPORTED_CONFIGURATIONS`. Switch the order so that `Release`
is listed first, as this is a better fallback than `Debug` for the
`RelWithDebInfo` and `MinSizeRel` configurations. See issue #16091.
This supplements the existing library checks, to
cater for the possibility that the libraries are
present but the headers are not. This can happen
when the Boost collections is split up into
multiple packages and not all are installed,
and will avoid the checks silently passing when
the build would subsequently fail.
Previously we added only NO_CMAKE_SYSTEM_PATH to find command calls.
Add NO_SYSTEM_ENVIRONMENT_PATH too so that paths found from system
environment variables are not considered either.
Depending upon the configuration, certain components may or may not
be installed, for example Boost.Regex, but other components may
still have header dependencies upon these components which will
obviously fail to work. Since we can't make a sensible
determination with the hardcoded dependency information, we
choose to interpret these dependencies less strictly.
The function _Boost_MISSING_DEPENDENCIES will look at the
user-supplied component list, check the dependency
information for each component using
_Boost_COMPONENT_DEPENDENCIES, and will add any missing
dependencies to the component list. This ensures that
all required components will be searched for.
The function _Boost_COMPONENT_DEPENDENCIES is used to query the
library dependencies for a given component for a given version of
Boost. This covers Boost releases from 1.33 to 1.59, using the
information generated by Utilities/Scripts/BoostScanDeps.cmake.
These cache entries introduced by commit 892b854f (FindBoost: Search for
debug and release libraries separately, 2015-01-26) should be marked as
advanced just as Boost_LIBRARY_DIR was. Also their _LAST values should
be tracked so changes can be detected reliably. Both of these are
handled by code looking in _Boost_VARS_LIB for a list of relevant
variables. Fix construction of this list that was broken by the above
commit.

Green Hills MULTI is an IDE for embedded real-time systems. The IDE's
product page can be found here:
http://www.ghs.com/products/MULTI_IDE.html
It supports cross compiling on ARM, Intel x86, and other architectures
with various operating systems. The IDE exists on Linux and Windows
host systems, but CMake will currently only generate the project files
on Windows host systems.
When using CMAKE_FIND_ROOT_PATH, FindBoost is able to find the first
component and cache the full path of the directory in Boost_LIBRARY_DIR
so that all components are looked for in same directory. The issue was
that, when looking for the other components, Boost_LIBRARY_DIR was
re-rooted against CMAKE_FIND_ROOT_PATH even though it was already a path
on the host. This change fixes this by disabling the re-rooting in the
find_library call when using Boost_LIBRARY_DIR as a hint.
