Since commit v3.9.0-rc1~17^2~4 (Compilers: Port to use default
cmake_record_lang_compile_features macros, 2017-05-10) we run full
per-language-standard feature detection for MSVC. This is not necessary
because the base mode for MSVC has all features we define except for the
meta-features for C++14 and above. Override the default C++ feature
detection macro for MSVC to run detection only once as before.
Fixes: #17274
Revert commit v3.7.0-rc1~25^2 (VS: Recognize VS/LLVM toolset names as
Clang, 2016-09-28). Since at least LLVM 5.0 the VS integration of the
LLVM toolchain now mimics cl and accepts MSVC-style command-line
arguments (unlike Microsoft Clang/C2).
Fixes: #17193, #17235
The `find_dependency` macro is designed to be called from Package
Configuration Files, not from Find Modules. The return() behavior is
particularly problematic for find modules. Document this more clearly.
Issue: #17257
91935d9e FPHSA: lower-case for cmake_parse_arguments + move config-mode related code

- The output file name of the `rcc` command get computed once
in the AUTOGEN initializer and is passed in the info file.
- The function name for the `-name` option of `rcc` gets computed
once in the AUTOGEN initializer and is passed along with the
other `rcc` options in the info file.
This is a large commit that serves multiple purposes
- Iterate source files only once and store all extracted
information in a cmQtAutogenDigest class that can be reused.
This is brings speed improvements because several properties
are only evaluated once. More that that it helps to avoid
duplication of code with non trivial files property checks.
- Fix the Visual Studio generator to use PRE_BUILD when possible.
- Convert `for( ... )` loops to C++11 range base loops where possible
(cmQtAutogen*.cxx only).
- String concatenation optimizations.

With the use of options `Boost_USE_DEBUG_LIBS` and
`Boost_USE_RELEASE_LIBS` it is now possible to skip searching for either
DEBUG or RELEASE Boost libraries.
This is useful if Boost is installed on the system in multiple
directories but only one of them should be used which only contains e.g.
the RELEASE libraries. Without this change the DEBUG libraries might be
found in the other directory which might not be desired at all.
Revert commit v3.9.0-rc1~41^2 (FindBoost: Simplify search in lists,
2017-04-23). It regressed the module by exposing issue #17257, but the
fix for that issue is not suitable for inclusion in a patch release.
It is simplest to revert the commit until the larger problem can be
addressed.
Fixes: #17252
Since NDK commit 90ec78ffd96b87cd75d82575587ead14d6494df1 (Remove Clang
toolchain path from setup.mk, 2017-05-31) the `setup.mk` files for Clang
no longer hold the path to the `toolchains/llvm` directory. It has been
the same since NDK r11, so use that as the default.
Fixes: #17253
The overhaul in commit v3.9.0-rc1~207^2~1 (FindOpenMP: Complete
overhaul, 2017-04-24) documented this variable but accidentally left it
unset.

The known keywords for each function are obtained by scraping the
documentation for lines matching a particular regular expression. In
commit 8842a027 (ExternalProject: Improve documentation, 2017-07-09),
the docs were overhauled and the COMMAND docs subsequently matched the
regular expression when they shouldn't have. This made COMMAND appear as
a true keyword, which thwarted the special handling logic elsewhere for
the intended use of COMMAND arguments.
This commit contains a workaround for issue #17229 to force a dependency
of the patch step on the update step to ensure a predictable step order.
Fixes: #17198
flang is a Fortran compiler built on top of clang [1]. Because flang
shares a lot of commonalities with clang, the flang module piggybacks
off the clang module and overrides certain options.
Add flang to Fortran compiler auto find list.
Update flang preprocessor macros to differentiate from PGI.
Add Flang-FindBinUtils.

Use `try_compile` instead of `try_run`. It is not clear why `try_run`
was ever needed, and it does not work during cross-compiling.
Update the check's source file to remove code associated with actually
running things. Also remove the ancient `__CLASSIC_C__` code path and
use a simple `int main(void)` as in `Modules/CheckIncludeFile.c.in`.
Fixes: #16920
