The CMAKE_FRAMEWORK_PATH and CMAKE_APPBUNDLE_PATH cache variables are
supposed to be used to generate the extra paths passed to pkg-config,

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The documentation of this variable in the CTest module is outdated

Green Hills MULTI is an IDE for embedded real-time systems. The IDE's
product page can be found here:
http://www.ghs.com/products/MULTI_IDE.html
It supports cross compiling on ARM, Intel x86, and other architectures
with various operating systems. The IDE exists on Linux and Windows
host systems, but CMake will currently only generate the project files
on Windows host systems.
Refactoring of content list that removes
use of find and sed to make listing algorithm

Patch also limits man pages handling to
locations listed in brp-compress rpm script

The UPPERCASE name was inconsistent with config-packages, the

components to be specified with names matching ExactCase.
The FOUND_VAR was only permitted to have two possible values, and

When SWIG_GET_EXTRA_OUTPUT_FILES checks to see if a source file exists

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

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.
The `binary_dir` variable is never set, so this is invalid. Instead, use
"." which all the other build commands use anyways. Also only set the
--config option if it is meaningful.

CPACK_RPM_<component>_PACKAGE_ARCHITECTURE variable allows

BuildArch must only be added to a spec file for a "noarch" package or

make it mandatory, adding a default value of native architecture (the
same as if no --target argument is present). Update the documentation
at the top of the file to make it mandatory.

code path is taken but tinfo is not found. However, since commit

Since jsoncpp 0.7.0 (2014-11-20) the upstream may provide a CMake
package configuration file such that find_package(jsoncpp) will find a
jsoncppConfig.cmake file. In order to avoid conflicting with this
(especially on case-insensitive filesystems), and since we always prefer
projects to provide package config files (that they maintain), it is
better to not provide FindJsonCpp publicly.
Move FindJsonCpp into a private source directory that is not installed
so that we can still use it for building CMake itself.

This bug caused c_function_prototypes to not be recorded at configure
time when compiling with -std=gnu99 or similar. In the case of feature
recording, that was not a problem, because the logic in
CMakeDetermineCompileFeatures.cmake currently assumes that a feature
present for an earlier standard is present for a later standard.
However, the detection strings are also used in WriteCompilerDetectionHeader,
so the feature macro has been defined to '0' when using a later language
dialect.
Fix that by not checking the existence of the __STDC_VERSION__ macro at
all when detecting C90 features.
If no compiler feature information is known for a given compiler
version, do not set a language standard default either. The two
settings must be recorded consistently.
When targeting Windows with a 64-bit architecture, use "$PROGRAMFILES64"

When loading the list of target support directories, read the file
with UTF-8 encoding since that is what CMake writes into the file.
This allows us to support international characters in the path to
the build tree containing the target support directories.
Add a GCOV_OPTIONS option to allow specification of custom flags. In
ctest_coverage gcov support, if you set CTEST_COVERAGE_EXTRA_FLAGS, they

-b and replace it with GCOV_OPTIONS. All other arguments remain the
same.
The "cmakexbuild" wrapper is not needed for Xcode 4 and above, and the
path to it may change when CMake moves. Avoid storing a specific path
to a build program in CMakeCache.txt and instead compute the value for
CMAKE_MAKE_PROGRAM on demand. However, if a user does set the value
explicitly then honor it.
This does for Xcode what commit v3.0.0-rc1~260^2~4 (VS: Switch to
internal CMAKE_MAKE_PROGRAM lookup by generators, 2013-11-15) did for

the build. In such cases, CMake prefers to record the relevant paths
from the environment and use them when invoking the build. That is not
currently done for the compilers on APPLE, so the compiler used is not
the one reported when running cmake:
$ DEVELOPER_DIR=/Applications/Xcode2.app/Contents/Developer/ cc --version
Apple LLVM version 6.0 (clang-600.0.51) (based on LLVM 3.5svn)
Target: x86_64-apple-darwin13.4.0
Thread model: posix
$ DEVELOPER_DIR=/Applications/Xcode.app/Contents/Developer/ cc --version
Apple LLVM version 5.1 (clang-503.0.38) (based on LLVM 3.4svn)
Target: x86_64-apple-darwin13.4.0
Thread model: posix
Update that now by querying Xcode for the correct compiler path if
the compiler located by ordinary means is located in /usr/bin.

f73718c9 Features: Enable writing of MSVC compiler feature header.

This topic was merged to master prematurely, so remove it.
In commit v3.1.0-rc1~113^2 (Use a more reliable regex for extracting
binary INFO strings, 2014-09-03) the matching of INFO: strings was made
more strict and no longer matches just "INFO:qnxnto". Use
"INFO:qnxnto[]" instead to conform to the new pattern.
When installing, MSMPI puts a trailing backslash in the MSMPI_BIN
environment variable. This causes trouble when concatenating in CMake
since the list separator is now escaped and no longer a list separator
due to the trailing backslash. Instead, use file(TO_CMAKE_PATH) to make
the path CMake-friendly.
The approach in commit v3.1.0-rc1~1^2 (Xcode: Fix compiler id detection
when code signing is required, 2014-10-22) still requires a code signing
key when targeting a real device. Instead set CODE_SIGNING_REQUIRED to
"NO" to tell Xcode not to sign at all. Drop the corresponding setting
of the code signing identity.
Since commit v2.8.8~173^2 (FindRuby: clean up querying variables from
Ruby, 2012-02-17) we query RbConfig::CONFIG first and, if the command
fails or its output equates to a false constant, then fall back to
querying Config::CONFIG.
Due to the above, an error condition exists with Ruby 2.2.0; when
querying RbConfig::CONFIG['TEENY'], the output of '0' will be discarded
since it matches the false constant '0'.
In previous versions this wasn't a problem, but Ruby 2.2 has completely
removed Config::CONFIG. This causes RUBY_VERSION_PATCH to be set to an
empty string and the Ruby version to be detected as '2.2.' (instead of
'2.2.0').
Fix the output check to explicitly look for an empty string before using
the fallback query method. (Someone more familiar with Ruby might be
able to deem the fallback as unnecessary and fully remove it.)

Notes:
VS2015 and above are the only MSVC versions to support cxx_final, so remove
usages from the tests, and instead only test for cxx_override.
VS2012 and above to conform to cxx_decltype_incomplete_return_types
proposal, but without support for auto return types the dcl.type.simple
example in the proposal doesn't compile.
VS2013 and above to conform to the updated cxx_contextual_conversions proposal,
but VS2010 and above pass the test.
Compilers such as MSVC have no explicit flags to enable C++11 mode,
it just is always on. So only run the link tests with compilers that require
a flag to specify the language version.
Initializer lists are only properly supported in 2015 and above.
Previous Visual Studio releases said they supported initializer lists
but silently produced bad code.
CMAKE_SYSTEM_PROCESSOR is not guaranteed to be defined (per
http://www.cmake.org/Wiki/CMake_Cross_Compiling), and when cross
compiling where it happens to be undefined, this module was broken.

Previously only the CMAKE_{C,CXX}_FLAGS_<CONFIG> flags were inspected
for relevant flags when compiling the intermediate link file. We need
to also consider the configuration agnostic flags, CMAKE_{C,CXX}_FLAGS
as well.
AppleClang does not support the cxx_thread_local feature, even
though it is based on a Clang version which does support the
feature.
http://stackoverflow.com/a/23850891/2428389
A possible reason for that is that thread_local might be used as
a variable in existing Apple SDK headers.
Extend the WriteCompilerDetectionHeader module to generate a define
for that feature with portability fallbacks. For the avoidance of
making it easy to write code which looks correct but which has odd
runtime behavior, don't set the define symbol at all if no
equivalent keyword is known.
The SunPro Fortran compiler uses "-F" instead of "-E" to request
preprocessing. The output does not go to stdout so use "-o" to
specify the output file.
This fixes the guess originally made by commit b6b37e30 (Makefile: Add
assembly and preprocessed targets for Fortran, 2014-11-05).
