Since commit ad502502 (cmMakefile: Track configured files so we can
regenerate them, 2013-06-18) cmMakefile::ConfigureFile records the
configured file as an output file generated by CMake. The intention is
that for make and ninja we can re-run CMake when one of the files it
generates goes missing. However, files configured temporarily in
CMakeTmp directories by Check* modules do not live past the CMake
invocation.
Teach cmMakefile::FinalPass to stop tracking files that don't
exist after we are finished generation.

Teach cmMakefile::ConfigureFile to skip tracking files with "CMakeTmp"
in their path, just like cmCoreTryCompile::TryCompileCode does to
avoid adding dependencies on temporary source files. In the future
we will need a more general filter to avoid recording as CMake
outputs any files that do not exist at the end of generation.
Currently when a configured file is removed from the build directory,
running the build command will not regenerate the file. Now detect
this and will rerun cmake properly when a user issues the build
command.
AddCMakeDependFile and AddCMakeOutputFile both store as std::string
and all calling sites use std::string. So instead of creating more
temporary objects, lets just use std::strings.
Refer users to the newer CMAKE_<LANG>_COMPILER_VERSION variables.
Use a more concise summary. Format the documentation to look
better in the "cmake --help-module" output.
When Boost_USE_STATIC_LIBS is ON we may complain that Boost libraries
cannot be found even when shared libraries are present. Update the
error message to tell the user explicitly that we want static libraries.

Through use of libarchive internally we support .zip files as well as
.tar format. The ExternalProject module makes use of this feature.
Document support officially.
Expose the internal system information API to the CMake language. For
example, it is useful to see how much memory the system has available to
estimate an upper limit of tests that can run in parallel.
Document the logic that parses for backward compatibility the old
variables that were used to control add_jar prior to named argument
support. In particular, document that the reason this logic exists is
for backward compatibility, and that new features do not need to add to
it.
