Divide the cmGlobalVisualStudio10Generator "PlatformToolset" member into
two members representing the generator-selected default toolset and the
user-specified CMAKE_GENERATOR_TOOLSET value. Prefer the user-specified
value, if any, and then fall back to the generator-selected default.
Drop the "Modules/CMakeVS*FindMake.cmake" files. Override the
cmGlobalGenerator::FindMakeProgram method for VS generators to use their
internal APIs to locate the build tool. Set the CMAKE_MAKE_PROGRAM as a
normal variable for use by project code, but do not cache it. This will
allow CMake and CTest to select the proper tool at build time.
Rename the Visual Studio >= 10 generators to indicate the version year:
Visual Studio 10 => Visual Studio 10 2010
Visual Studio 11 => Visual Studio 11 2012
Visual Studio 12 => Visual Stduio 12 2013
Report the names with the year to the list of available generators so
that the cmake-gui drop-down shows the years. When selecting a
generator from the "-G" option or from an existing CMAKE_GENERATOR cache
entry, recognize names without the years for compatibility and map them
to the names with years.
Update the generator names in the cmake-generators.7 manual.
Since we do not need the information about the target architecture
we can use the PlatformName only to specify the this information.
This also removes setting of the MSVC_*_ARCHITECTURE_ID variable
which is not required, because this variable gets set by the
compiler detection code in CMAKE_DETERMINE_COMPILER_ID_CHECK().
Add to the brief documentation of the Visual Studio 10, 11, and 12
generators the corresponding VS product year. Clarify that VS11 is for
Visual Studio 2012, and VS12 is for Visual Studio 2013.
The VS version we generate in the .sln header is used by VS when opening
the file through Windows Explorer and possibly elsewhere. Fix our
generators to use version strings known to VS to avoid a drop-down box.
For VS 10, since commit 4f96af44 (Fix VS 10 .sln files for Windows
Explorer, 2009-10-22) we use "Visual Studio 2010" instead of just
"Visual Studio 10". This is correct except that for the Express edition
we need "Visual C++ Express 2010".
For VS 11, since commit f0d66ab4 (VS11: Fix comment generated at the top
of *.sln files, 2011-10-20) we use "Visual Studio 11" in the .sln header
but the preferred value is "Visual Studio 2012" (just as the first
commit mentioned above fixed for VS 10). Also for the Express edition
we need "Visual Studio Express 2012 for Windows Desktop".
Solution folders are supported as read-only in the VS11 Express
Edition, so do not prohibit their use just because we detect the
express edition (as we did in the VS10 generator).

Use the registry entries that vsvars32.bat uses to detect the location of
MSBuild.exe in the framework directory. Invoke MSBuild with the option
/p:VisualStudioVersion=$version
so it knows from which VS version to load the system build rules. Teach
cmGlobalVisualStudio11Generator to set its ExpressEdition member using the
registry.
Teach Windows-cl.cmake to use CMAKE_(C|CXX)_COMPILER_VERSION to set the
"MSVC##" and MSVC_VERSION variables. It no longer needs the IDE generator
to dictate the version or to detect the version by running the
command-line tool for NMake and Ninja generators. Drop configuration of
CMakeCPlatform.cmake and CMakeCXXPlatform.cmake from Windows-cl.cmake.in
because all the results it saved are now cheap to compute every time.
Since the parent commit the local generator Version ivar may be
compared for ordering. Convert comparisons:
"==VS10" becomes ">=VS10"
"!=VS10" becomes "< VS10"
to support an explicit enumeration value for VS11 with no change
in behavior.
