This was added without explanation by commit v2.8.2~1138 (Add initial XL
C compiler flags for safer builds, 2009-09-30). It is not consistent
with our default C++ flags for XL and disables several optimizations, so
drop it from our default flags for C.

Add a TestLoad setting to CTest that can be set via a new --test-load
command-line option, CTEST_TEST_LOAD variable, or TEST_LOAD option to
the ctest_test command. Teach cmCTestMultiProcessHandler to measure
the CPU load and avoid starting tests that may take more than the
spare load currently available. The expression
<current_load> + <test_processors> <= <max-load>
must be true to start a new test.

Move the Ld invocation match expression from CMakeDetermineCompilerId

Replace caret-headers with double-quote-headers and replace dash-headers

If a Windows resource (.rc) source file is included in a STATIC library,
the VS "link" tool will process the compiled ".res" file and needs to know
the target architecture. Without it, we may get a LNK4068 warning and
possibly a LNK1112 error. Add /machine: to the default static library
flags to give the link tool the information it needs.
When constructing the "id_src" value for substitution into VS or Xcode
compiler id projects, the input "src" variable already contains the file
name with no path so we do not need get_filename_component. We know
this because CMAKE_DETERMINE_COMPILER_ID_WRITE already references
"${src}" with this assumption.

At least some versions (e.g. C++ Builder 5) of the bcc32 linker are known to
write temporary files with a constant name to the current directory (e.g.
"turboc.$ln"). (This can be verified by using Process Monitor to watch the
file writes that bcc32 / ilink32 / implib make). This causes problems with
some generators that keep a constant current directory and run concurrent
linkers.
For example, the Ninja generator, by default, always has the current directory
set to the top of the build tree - resulting in conflicts between the linkers
that are simultaneously trying to write to "turboc.$ln". Symptoms include
direct errors regarding the "turboc.$ln" file, or later build steps failing due
to corrupted output from previous links that happened to link "successfully."
This is not a problem for the Borland Makefiles generator which does not
run jobs in parallel. For the Ninja generator, work around this problem
by using a link job pool of size 1.
The Concurrent Fortran compiler (ccur.com) is available on Linux and can
be used much like the GNU Fortran compiler. Currently it has no
preprocessor symbols to identify it so we need to detect it by matching
compiler output.

Some compilers can only be distinguished by their compilation output
rather than preprocessor symbols or special flags. Add infrastructure
to determine the compiler id by matching output.
Callers of CMAKE_DETERMINE_COMPILER_ID initialize the
CMAKE_${lang}_COMPILER_ID to unset so we can check it at the end of each
loop iteration instead of the beginning. This approach allows us to
break out of the loop as soon as we succeed. It will also allow checks
to be added in more places within the loop later.
Teach CMAKE_DETERMINE_COMPILER_ID to optionally try detecting the
compiler id using some given flags before trying to detect it with no
special flags. This will be useful for Fortran detection to distinguish
some compilers that use the preprocessors of others but have no macro of
their own by getting verbose output.
Teach the module to handle SYSCONFDIR and LOCALSTATEDIR properly if
CMAKE_INSTALL_PREFIX is set to `/` or `/usr` -- i.e. as expected by GNU
Coding Standard (i.e. set SYSCONFDIR to `/etc` and `LOCALSTATEDIR` to
`/var`). Also if CMAKE_INSTALL_PREFIX is set to /opt/pkg, `SYSCONFDIR`
must be set to `/etc/opt/pkg` and `LOCALSTATEDIR` to `/var/opt/pkg`
according to FHS.
Otherwise using a "cc -> ccache" or similar symlink as the compiler
causes FindCUDA to select ccache as the host compiler. Update the logic
added by commit v3.1.0-rc1~354^2 (FindCUDA: Fix OSX Clang & no C
language enabled, 2014-06-12) to apply only in the specific case it is
needed.
Revert commit v3.3.0-rc1~435^2 (Windows-GNU: Do not tell find_library to
treat '.dll' as linkable, 2015-02-18). MinGW tools support linking to
'.dll' files directly and many non-CMake build systems still do not
provide a separate '.dll.a' file.
In commit v3.3.0-rc1~132^2 (FindwxWidgets: Search for wx-config-3.0 in
addition to wx-config, 2015-04-29) we added a second (versioned) name to
the find_program call. Specifying multiple names requires use of the
NAMES option. Add it now. While at it, also add versioned names for
2.9 and 2.8.
Check for this flag explicitly in the --help output before using it. It
turns out there are some versions of the tool that support --version but
not --ignore-missing-info.
Honor the GIT_SUBMODULES option added by commit v3.0.0-rc1~92^2
(ExternalProject: Add option GIT_SUBMODULES, 2014-01-09) during the
'git submodule init' step to avoid initalizing all modules since we
are only going to update the specified subset anyway. This will
be useful for project repositories that have many submodules
(e.g. https://github.com/boostorg/boost).

These cache entries introduced by commit 892b854f (FindBoost: Search for

Do not force a specific policy version in the module because it prevents
projects from setting newer policies to NEW. In particular, projects
may want to set CMP0056 to NEW to affect any try_compile calls in this
module.
Use of this was added in commit v2.8.2~714 (FortranCInterface: Use CMake
2.8.0 behavior, 2009-11-17) in order to set CMP0007 to NEW. Simply set
this policy explicitly instead.

The actual issue surfaces when a single custom command's MAIN_DEPENDENCY
is listed in more than one target; this issue will have to be addressed
independently.
The documentation of this variable in the CTest module is outdated

I was previously appending to nvcc_flags inside the file loop. This
caused the flag to be appended multiple times which freaks out nvcc.
Now the flag is specifically handled per file.
A previously undocumented feature allowed overriding the format
specified to CUDA_WRAP_SRCS with a source file property called
CUDA_SOURCE_PROPERTY_FORMAT. I added documentation for this feature as
well as added the ability to let nvcc compile any file regardless of
type if this property was found.
In addition, I also fixed a couple of bugs with the calls to
_cuda_get_important_host_flags that weren't garding the arguments with
"" to prevent empty values from causing errors.
If the host flags contain a c++11 flag (at least for gcc), then we can't
automatically propagate to nvcc it using -Xcompiler. This is because
nvcc can't use any C++ only flags. Instead we find this flag and add it
to nvcc's flags (it has a special flag for dealing with c++11 code) and
remove it from the host flags.

VS 2013 originally claimed to support initializer lists but a bug was
found in which it generated bad code silently. For this reason we
previously considered support to not be present. However, Update 3 adds
a hard error on cases that previously generated bad code, so it is now
safe to use initializer lists with VS 2013 Update 3 or greater. At
worst a compiler error will be issued in the cases that do not work, but
that is no different from any other compiler-specific workaround a
project code may need.
Beginning in CUDA 5.5 a static version of the cuda runtime library
became available. Since nvcc defaults to using this library over the
shared version, FindCUDA will also default to using this version. There
are many advantages to using the static version (most importantly to
avoid conflicts with multiple versions when building a CUDA based
library). Offer a CUDA_USE_STATIC_CUDA_RUNTIME option to control
this behavior.
RPM packages can contain symbolic links to relative paths - including
support for multiple relocation paths through generation of post install
relocation scripts. Add basic support with limitations described in
documentation.
Add the dependency on the main swig input source file as a normal
DEPENDS option. We cannot use MAIN_DEPENDENCY because if there are
multiple target languages then multiple custom commands would want to
use the same MAIN_DEPENDENCY, but at most one custom command may specify
a given source file as its MAIN_DEPENDENCY. Exposed by a CMP0057
warning.
Extend the ``DATA{Dir/,...}`` syntax with a new ``RECURSE:`` option
to enable recursive matching of associated files. This will allow
an entire directory tree of data to be referenced at once.
Extend the _ExternalData_arg_find_files signature with an option to
specify the kind of file(GLOB) operation to be performed. Set
CMP0009 to NEW so that GLOB_RECURSE does not follow symlinks.
Teach the Xcode generator that ONLY_ACTIVE_ARCH=YES means to use ARCHS,
and that the default of ONLY_ACTIVE_ARCH=NO means to use NATIVE_ARCH and
ignore ARCHS. In the latter case there is no reason to generate ARCHS.
