Create a <LANG>_INCLUDE_WHAT_YOU_USE target property (initialized by a
CMAKE_<LANG>_INCLUDE_WHAT_YOU_USE variable) to specify an IWYU command
line to be run along with the compiler.
Add an internal "cmake -E __run_iwyu" mode to wrap the compiler call.
Run a given include-what-you-use command line with the compiler options
and report a warning if it finds anything. Then run the real compiler.

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.

Use of this was added in commit v2.8.2~539 (New CheckTypeSize for OS X
Universal Binaries, 2009-12-17) and updated in commit v3.1.0-rc1~511^2~1
(Do not change minimum required version in modules, 2014-05-07). The
history does not clearly explain why a specific policy version was
introduced. If specific policies need to be NEW then we can add
explicit settings for them.

This option was once used by our OS X package installer to create
symlinks at install time. Since switching to the DragNDrop installer
we no longer use this option.
The backtrace will soon not be implemented in terms of a stack of
cmListFileContext objects. Keep the cmListFileContext in the API
for convenience for now.
The PushTLLCommandTrace method is called once per link item for a single
target_link_libraries command. Avoid storing copies of identical
execution contexts and rely on the uniqueness while printing output.
Our <LANG>_COMPILER and <LANG>_<TARGET_TYPE>_LINKER rule generation has
access to a specific cmTarget so the results may depend on it. Instead
generate separate rules for each target using an encoded target name.
In particular, this makes CTEST_USE_LAUNCHERS report proper target
information.
