This patch adds two macros cmake_push_check_state() and
cmake_pop_check_state(), which can be used to save and restore
the contents of the CMAKE_REQUIRED_xxx variables.

In find-package mode, cmake executes Modules/CMakeFindPackage.cmake,
which calls find_package(), and this is then evaluated in cmake.cxx,
which prints an appropriate message to stdout, so it can be used
e.g. in a normal Makefile:
$ /opt/cmake-HEAD/bin/cmake --find-package -DNAME=JPEG
-DCOMPILER_ID=GNU -DLANGUAGE=C -DMODE=EXIST
JPEG found.
$ /opt/cmake-HEAD/bin/cmake --find-package -DNAME=JPEG
-DCOMPILER_ID=GNU -DLANGUAGE=C -DMODE=COMPILE
$ /opt/cmake-HEAD/bin/cmake --find-package -DNAME=JPEG
-DCOMPILER_ID=GNU -DLANGUAGE=C -DMODE=LINK
-rdynamic -ljpeg

A common mistake when using custom commands is to list the output of a
command in multiple targets that may build in parallel. Warn against
this case in the documentation and suggest a better approach.
This reverts commit 1088b0278e.
Wrapper dependency scanning (fix for #4147) does not work at CMake
configuration time if an input file is provided by a custom command
(regression #12307). Revert to original behavior until a solution is
found.
8555c2b Look for VCExpress as a possible build tool as well as devenv.
ed0075b Use relative paths for custom command inputs.
38368d5 Revert "With very long file names, VS 2010 was unable to compile files."
8cd66dc Use devenv instead of msbuild for vs2010.
For source files we use full paths. This allows for longer directory
names with VS2010. However, the use of full paths causes the GUI
to not display the custom commands.
As discussed, this adds a switch CMAKE_DISABLE_FIND_PACKAGE_<name>,
which, when set to TRUE, keeps the find_package() command from executing.
When the package is REQUIRED at the same time, an error is generated.

If FindMPI can't interrogate any of the available compilers, it attempts to compile simple MPI
programs with CMAKE_${lang}_COMPILER. If this works, it uses that as MPI_${lang}_COMPILER.
This allows MPI to be discovered on Cray XT/XE systems, where modules are used and cc, CC, and ftn
compilers *are* MPI compilers.
