Document these variables.
Change our convention for setting these variables from:
set(CMAKE_C_FLAGS_INIT "...")
to
string(APPEND CMAKE_C_FLAGS_INIT " ...")
so that any value previously set by a toolchain file will be used.
Automate the conversion with:
sed -i 's/set *(\(CMAKE_\(C\|CXX\|Fortran\|RC\|ASM\|${[^}]\+}\)_FLAGS\(_[^_]\+\)\?_INIT \+"\)/string(APPEND \1 /' \
Modules/Compiler/*.cmake Modules/Platform/*.cmake
and follow up with some manual fixes (e.g. to cases that already
meant to append). Also revert the automated changes to contexts
that are not protected from running multiple times.
Migrate from the old `<os>-<cc>.cmake` layout to the modern
`<os>-<id>-<lang>.cmake` layout. Keep settings common to C and C++ in a
`Windows-OpenWatcom.cmake` helper module with an include blocker.
For now just add both C and CXX settings in the helper module.
Refactor options out of `Modules/Compiler/Intel-{ASM,C,CXX,Fortran}.cmake`
into a common helper in `Modules/Compiler/Intel.cmake`. Condition
them to be used only on non-Windows hosts where the Intel compiler
is GNU-like instead of MSVC-like.
Previously this worked only because the options were later overridden
by `Modules/Platform/Windows-Intel*.cmake`, but it is cleaner to not
set the options in the first place.
Teach `Modules/Platform/Windows-MSVC.cmake` not to use MSVC options
for Fortran. We use the `__windows_compiler_msvc` for the Intel
Fortran compiler on Windows for other settings, but we do not want
the flags.

We no longer define the ZLIB_LIBRARY cache entry, so we should not mark
it as advanced either. We only use this variable when someone else
defines it in order to remain compatible with older versions of this
module, but we never create the entry ourselves anymore.
Extend the optimization from commit v3.4.0-rc1~264^2 (GetPrerequisites:
Optionally filter "objdump" output for speed, 2015-07-29) to work
on Windows by using `findstr` in place of `grep`.
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.
In commit v3.6.0-rc1~279^2~10 (VS: in Clang/C2 toolset, setup correct
compiler settings, 2016-02-18) a flag mapping was added for the clang
`-Os` flag. However, this collides with a mapping we already had for
the MSVC flag of the same name. This is a symptom of a larger problem
in that the VS generators need a per-toolset flag map (issue #16153).
For now, simply drop the new mapping and drop `-Os` from clang compiler
flags in the MinSizeRel configuration.
