These were added by commit v3.8.0-rc4~4^2~1 (RC: Add missing
CMAKE_RC_FLAGS_<CONFIG> entries to cache, 2017-03-28) and should be
advanced as they are for other languages.
Latest wxWidgets git master version and the upcoming 3.1.1 release requires
linking with shlwapi and version DLLs. As this does no harm when using the
previous versions, just do it unconditionally.
The `ld` tool in Xcode 8.3 now has a `-lto_library <path>` flag. Ignore
the flag instead of accidentally parsing it as `-l` with `to_library`.

Intel 17.0.2 on UNIX introduced a regression from 17.0.1 in its
definition of `__cpp_constexpr` in `-std=c++14` mode. It incorrectly
defines it as `200704` instead of the expected `201304`. Fix our
feature detection table to account for this.
The change in commit v3.8.0-rc2~7^2 (ExternalProject: Run `git
checkout` with `--` to clarify arguments, 2017-02-24) broke the case of
`GIT_TAG some-remote-branch` because an explicit `--` means that the
preceding argument is a tree-ish instead of a branch. Revert the change
and leave a comment.
Fixes: #16763
The sdcc compiler no longer defines the `SDCC` preprocessor macro.
Instead `__SDCC_VERSION_MAJOR` and similar component-wise macros are
defined. Use them instead if defined.
Issue: #16746
In commit v3.8.0-rc1~304^2 (MSVC: Do not define _DEBUG explicitly when
using /MDd, 2016-11-15) we removed the `_DEBUG` preprocessor definition
from MSVC C and C++ flags because the `cl` compiler automatically
defines it in Debug builds anyway. However, the VS generators propagate
C preprocessor definitions to the RC (Windows Resource Compiler) tool.
This means that we used to explicitly define `_DEBUG` for RC debug
builds. Therefore existing project code may expect the definition to be
there even though the `rc` compiler itself does not implicitly define
`_DEBUG` in debug builds.
Add the `_DEBUG` flag to the default `CMAKE_RC_FLAGS_DEBUG` instead
to restore this definition for RC debug builds. This also makes it
available consistently in VS, Ninja, and Makefile generators.

Use our undocumented `cmake_host_system_information` query to find the
VS 2017 installation directory by asking the VS installer tool. Then
look relative to that for the redist directory.
Fixes: #16737
VS 2017 (VS 15) places its redist DLLs in `Microsoft.VC150.*`
directories but still uses version number `140` in the DLL names. The
redist directories now have version numbers in their name, and the MSVC
and MFC runtime DLLs may be in directories with different versions.
Fill out our logic to handle this.
For now assume we are given the `MSVC_REDIST_DIR` value as a cache
entry. Unfortunately we cannot yet find the VS 2017 MSVC redist
directory automatically since there is no registry entry for the VS
installation. Later we will have to use `cmVSSetupHelper` for this.
Issue: #16735
Each `MSVC${v}_*_DIR` variable is only ever used with one value for
`${v}` within a given build tree. Drop the `${v}` version component
from the variable names.
For a given `MSVC_VERSION` our macros were each called at most once.
Replace them with a single code path that is parameterized over what
was the macro argument.
Some projects may not be prepared to use the imported targets defined by
the HDF5 package configuration file. Give users a way to skip this part
of the search.
