Some commands on Windows do not understand forward slash paths and
require backslashes. In order to help projects generate shell
invocations of such commands, provide a generator expression to convert
paths to the shell-preferred path format for the current generator.
This will allow custom commands to generate paths the same way CMake
does for compiler command invocations.
The changes in commit 47b060ae (CPackDeb: allow empty directories in
component packages, 2015-09-21), commit b58de9fe (CPack: allow packaging
of empty directories, 2015-09-21), and commit b761e90d (CPack: remove
accidental changes, 2015-09-22) regressed packaging of CMake itself.
Revert the changes until they can be revised and rebased on other
changes that make additional fixes.

This causes a warning in C mode, and entirely fails in C++ mode:
CMake/Modules/CheckForPthreads.c: In function ‘runner’:
CMake/Modules/CheckForPthreads.c:34:27: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
printf("%d CC: %d\n", (int)args, cc);
^
Use %p to print out a pointer value, which will not cause any problems.
While at it, also add a branch using CheckIncludeFileCXX. Also give a better
error message if no supported language is enabled. C++ support isn't working
yet, but it has never worked.
When parsing digits we know our `c - '0'` expression results in a
non-negative value due to preceding conditions. Simply cast the result
to UInt. This fixes compilation on SolarisStudio 12.4.
In TryCompileCode we construct an internal argv[] vector that needs to
have a fake argv[0] so our internal cmake command line looks like a real
command line. Fix construction of the fake argv[0] when try_compile is
called without the CMAKE_FLAGS argument. Otherwise the first internal
-DVAR=val argument that we use to pass information like
CMAKE_OSX_SYSROOT is ignored.
Commit 7235334a (Project: Determine default language dialect for the
compiler., 2015-09-15) introduced a mechanism to determine the default
dialect used for the running compiler. If conditions in
the <CompilerId>-<Lang>.cmake file are such that compile features for
that version of the compiler should be supported, the _DEFAULT_STANDARD
is set to the computed value.
However, the CMakeForceCompiler module allows users to bypass execution of the
compiler by CMake. In that case, do not set the _DEFAULT_STANDARD variable at
all, which effectively disables the compile-features where the module is used.
No compile features have ever been recorded where the module is used so no
functionality is lost.
The changes in commit c96fe0b4 (cmake: Add -W options to control
deprecation warnings and errors, 2015-07-28) fail to account for
-Wdev warnings produced by places in CMake other than message().
This causes a regression in which -Wno-dev fails to suppress such
warnings. Revert the feature until it can be revised accordingly.
