Bill Hoffman 49948f7221 ctest_memcheck: Add support for ThreadSanitizer
This commit adds support for ThreadSanitizer to ctest.  ThreadSanitizer
is part of the clang compiler and also gcc 4.8 and later. You have to
compile the code with special flags. Then your code gets the the
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.

custom command in an OBJECT library.

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.

COMPILE_FEATURES in the link implementation is not lower than that
provided by the INTERFACE of the link implementation.  This is

the affected configurations are as restricted as possible to allow
for easy testing while extending the features vector in only one

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.

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.

Stephen Kelly 913394af24 cmTarget: Add CXX_STANDARD and CXX_EXTENSION target properties.
These are used to determine whether to add -std=c++11, -std=gnu++11
etc flags on the compile line.

Extend the cmGeneratorExpressionDAGChecker with an interface
returning the name of the top target.  Use that to determine
when there is a DAG violation, as required by the RunCMake.Languages
tests.

Stephen Kelly 5de63265e3 Genex: Only evaluate TARGET_OBJECTS to determine target sources.
The output of this expression may contain macros for IDEs to replace
such as $(Configuration), $(CURRENT_ARCH) etc.  To avoid generating
content which is not usable in other contexts, report an error if
there is an attempt to use it in other contexts.

This commit may be reverted in the future if a solution to the
above difference is implemented.

Stephen Kelly e5da9e51d0 cmTarget: Allow any generator expression in SOURCES property.
Remove use of UseObjectLibraries from Makefile and Ninja generators. It
is not needed now because those generators use GetExternalObjects
which already contains the objects from object libraries.

The VS10 generator calls both the UseObjectLibraries and the GetExternalObjects
methods. Ensure that duplicates are not created by skipping objects
from object libraries in handling of GetExternalObjects.

Similarly, fix VS6, VS7 and Xcode object handling by skipping
external objects from OBJECT_LIBRARY usage as appropriate.

The error message in the BadSourceExpression1 test is now reported
by the generator expression evaluator, so it has different text.

Brad King a41c0a9dcb Do not warn by default when policy CMP0025 or CMP0047 is not set
These policies are triggered by the use of a particular compiler rather
than outdated CMake code in a project.  Avoid warning in every project
that enables a language by not displaying the policy warning by default.
Add variable CMAKE_POLICY_WARNING_CMP<NNNN> to control the warning
explicitly; otherwise enable the warning with --debug-output or --trace.

This breaks with strict policy convention because it does not provide
developers with any warning about the behavior change by default.
Existing projects will continue to build without a warning or change in
behavior.  When a developer changes the minimum required version of
CMake in a project to a sufficiently high value (3.0), the project will
suddenly get the new compiler id and may break, but at least the
breakage comes with a change to the project rather than the version of
CMake used to build it.

Breaking strict policy convention is worthwhile in this case because
very few projects will be affected by the behavior change but every
project would have to see the warning if it were enabled by default.

Brad King d339653eaf Help: Revise and format policy CMP0025 and CMP0047 docs
Add inline reST markup as appropriate.  Word CMP0047 docs more like
those of CMP0025.  State explicitly that the policies must be set
before the project or enable_language command calls.
