Geoff Viola 48004d9dbe Add a 'Green Hills MULTI' generator on Windows
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.

Brad King 882f48e5ba Link libraries by full path even in implicit directories
When CMP0003 was first introduced we wanted to link all libraries by
full path.  However, some projects had problems on platforms where
find_library would find /usr/lib/libfoo.so when the project really
wanted to link to /usr/lib/<arch>/libfoo.so and had been working by
accident because pre-CMP0003 behavior used -lfoo to link.

We first tried to address that in commit v2.6.0~440 (Teach find_library
to avoid returning library paths in system directories, 2008-01-23) by
returning just "foo" for libraries in implicit link directories.  This
caused problems for projects expecting find_library to always return a
full path.  We ended up using the solution in commit v2.6.0~366 (...
switch library paths found in implicit link directories to use -l,
2008-01-31).  However, the special case for libraries in implicit link
directories has also proven problematic and confusing.

Introduce policy CMP0060 to switch to linking all libraries by full path
even if they are in implicit link directories.  Explain in the policy
documentation the factors that led to the original approach and now to
this approach.

Brad King aa2ba12164 VS: Use $(ConfigurationName) as CMAKE_CFG_INTDIR in VS 7, 8, 9
This will allow us to use a value other than just the config name
for the project OutputDirectory setting used for $(OutDir).

Also use $(ConfigurationName) instead of $(OutDir) for the link
directory configuration suffix since that is a hard-coded instance of
a use case for CMAKE_CFG_INTDIR.

Brad King ab9fa54d48 Xcode: Switch to internal CMAKE_MAKE_PROGRAM lookup by generator (#15324)
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
Visual Studio generators.

Add CMake Policy CMP0056 to activate this behavior in a compatible way,

for each policy setting.

Ben Boeckel ceecd7902f cmMakefile: store the number of last matches in a CMake var
With PushScope and PopScope, keeping track of another bit of data for

Define the 'cmake -A' option to set CMAKE_GENERATOR_PLATFORM

the name '-A' for "platform" because '-P' is already taken, and
in the common use case the "platform" is actually an architecture
(e.g. x64).

Teach the RunCMake test infrastructure to use -A to pass the generator
platform.  Extend the RunCMake.GeneratorPlatform test with a case to
verify that the -A option cannot be repeated.

that it is rejected when the generator does not support a user setting.

ThreadSanitizer ability built into it. To pass options to the
ThreadSanitizer you use an environment variable. This commit teaches
ctest to parse the output from ThreadSanitizer and send it to CDash.

Brad King 528e8af19f Allow a toolchain file to specify a generator toolset
Delay use of CMAKE_GENERATOR_TOOLSET until the CMakeSystem.cmake
file has been configured and loaded during the first project() or
enable_language() command.  This gives the toolchain file named by
CMAKE_TOOLCHAIN_FILE a chance to set CMAKE_GENERATOR_TOOLSET.  This
point is still early enough to set the generator toolset prior to
the initialization of any languages that might use the toolset.

The cmake::GeneratorToolset member variable remains an indication
of what was specified by the -T option or loaded from the cache.
It does not need to be updated based on the toolchain file setting.
The cmMakefile::TryCompile can still pass cmake::GeneratorToolset
into the inner instance because the try-compiled project will do
platform and language initialization using the CMakeSystem module
configured for the outer project.

Extend the RunCMake.GeneratorToolset test with cases that use a
toolchain file to set CMAKE_GENERATOR_TOOLSET.

Stephen Kelly 10f33eee1d Features: Add cxx_variadic_templates.
Expect cxx_variadic_templates to implement N2555.

N2555 is essentially a bugfix and predates most compiler releases which
aimed to experimentally support variadic templates.

Stephen Kelly 8ed59fc207 Add target_compile_features command.
This can be used to set the compiler features required by particular
targets. An error is issued at CMake time if the compiler does not
support the required feature. If a language dialect flag is required
by the features used, that will be added automatically.

Base the target_compile_features command on cmTargetPropCommandBase. This
gives us 'free' handling of IMPORTED, ALIAS, INTERFACE, non-compilable
and missing targets.

Stephen Kelly 5412deded1 cmTarget: Transitively evaluate compiler features.
Extend the interface of the target_compile_features command with
PUBLIC and INTERFACE keywords. Populate the INTERFACE_COMPILER_FEATURES
target property if they are set. Consume the INTERFACE_COMPILER_FEATURES
target property from linked dependent targets to determine the final
required compiler features and the compile flag, if needed.

Use the same pattern of origin-debugging which is used for other
build properties.

Stephen Kelly f97bf4370c Features: Add cxx_auto_type.
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.
