Old versions of aCC need a special compiler flag to get full C++98 template
support as e.g. CMake itself or the Complex and ComplexOneConfig tests need.
The same versions need a special flag to get a proper C++ library, too.
When the primary source tree path named by a DATA{} reference does not
exist, produce an AUTHOR_WARNING instead of a FATAL_ERROR. This is
useful when writing a new DATA{} reference to a test reference output
that has not been created yet. This way the developer can run the test,
manually verify the output, and then copy it into place to provide the
reference and eliminate the warning.
If the named source tree path is expected to be a file but exists as a
directory, we still need to produce a FATAL_ERROR.
Generalize the change from commit 39d0ade0 (Windows-GNU: Support
duplicate object names in large archives, 2014-04-14) to the default
archive rules. These rules have used an incremental append approach
since commit v2.8.0~1856 (Build large archives incrementally,
2008-08-04). Switch from "ar r" to "ar q" to be sure we always append
objects instead of replacing them.
Extend CMAKE_PLATFORM_IMPLICIT_LINK_DIRECTORIES with these paths. We
already have the equivalents under /usr. Systems that have these
directories have their dynamic loaders configured already. Do not allow
them to appear in the RPATH explicitly.

Since commit v2.6.0~388 (Added build rule variables
CMAKE_<LANG>_ARCHIVE_..., 2008-01-29) we use separate "ar cr ..." and
"ar r ..." steps to incrementally add a large list of object files to an
archive. Since the "r" command replaces existing objects of the same
name in an archive, if multiple objects have the same file name and
appear in separate append steps then one overwrites the other. Instead,
use "ar cq ..." and "ar q ..." to always append to the archive.
We already remove the archive before creating it so this will not cause
objects to be appended to existing archives on incremental rebuilds.
The matches have already been calculated and can simply be taken from
CMAKE_MATCH_n variables. This avoids multiple compilations of the same or very
similar regular expressions.
Warn project developers at runtime that the module should not be used
anymore. Issue the diagnostic only when the project requires a new
enough CMake to use the alternative. Honor the
CMAKE_(ERROR|WARN)_DEPRECATED settings.
Update the logic added by commit 2f9ad7c6 (Fix FindMPI for the intel
compiler on linux, 2012-03-20) to use the implicit link directories for
the current ${lang} instead of hard-coding C or CXX which may not be
enabled. This is necessary for Fortran-only projects.

7147ed5c CMakeRCInformation: Recognize 'windres' tools with '.' in name (#14865)
db924e00 CMakeRCInformation: Do not mention 'Fortran' in documentation
A 64-bit MinGW windres is named "i686-w64-mingw32.shared-windres". The
get_filename_component NAME_WE mode may strip the ".shared-windres" part
and cause the result to no longer contain "windres". Instead, match the
"windres" name in the full CMAKE_RC_COMPILER value first, and use the
get_filename_component code path only for other resource compilers.
Use the CMAKE_MATCH_* variables to simplify matching logic. Match
either 3 or 4 version components. Do not fail when there are only three
components available.
Expect cxx_variadic_templates to implement N2555.
N2555 is essentially a bugfix and predates most compiler releases which
aimed to experimentally support variadic templates.
Record the availability of this feature for GNU 4.8 on (UNIX AND
NOT APPLE) only. In the future, availability can be recorded for
earlier GNU, for other platforms and for other compilers. Initially
the affected configurations are as restricted as possible to allow
for easy testing while extending the features vector in only one
dimension.
The error message when using the set_property API directly is not
very good, but follow up commits will provide origin debugging of
the property and a target_compile_features command which will
provide a configure-time backtrace when possible.
Add a feature test using the compiler macros and the preprocessor to
determine available features.
Add a CMAKE_CXX_COMPILE_FEATURES variable which contains all features
known to the loaded compiler, and a CMAKE_CXX_KNOWN_FEATURES variable
containing all features known to CMake. Add language standard specific
variables for internal use to determine the standard-specific compile
flags to use.
This will be extended to other languages in the future. Follow-up
commits will add features which will be recorded by the feature test.
