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.
Without this, regular swig (not 2.0) executable is not found
automatically.
Commit 55b7c87e (Add support for new swig 2.0 application, 2011-03-28)
added support for finding swig 2.0 at the (accidental) expense of not
finding 1.x. Fix this regression.
The workaround added by commit 7e92f0b4 (Hack to make echo command work
properly in mingw32-make, 2006-10-05) and updated by commit 69356d8a
(Juse use cmake -E echo instead of the native echo, 2006-10-13) no
longer seems necessary with modern mingw32-make. Furthermore it slows
performance due to the time spent loading a cmake process instead of
plain echo.
Patch from Aaron C. Meadows
Adds support for detecting VS 2010 SP1
Also improves performance using CMAKE_CXX_COMPILER if it is available
and for robustness falls back using try_compile() and try_run()
Do not require the C language to be enabled to do lib->lib64 conversion.
The check was originally added by commit a5825cd1 (check in new find
stuff, 2006-03-02) to ensure that CMAKE_SIZEOF_VOID_P is set. Since
commit 3fdf1411 (FIND_LIBRARY should not require CMAKE_SIZEOF_VOID_P,
2008-02-11) the code following the check does not fail when the variable
is not set, so just remove the original check. This allows conversion
for any language that is enabled so long as the address size is known.

1ed19bc multiarch: Set CMAKE_LIBRARY_ARCHITECTURE_REGEX for Linux|Hurd|kFreeBSD
52a6ed2 Test find_package multiarch support (#12037)
b41ad3b Teach find_(library|package) about Linux multiarch (#12037)
Fix typo introduced by commit e28c16b4 (Split GNU compiler information
files, 2009-12-02).

* Fix linux CMAKE_LIBRARY_ARCHITECTURE_REGEX to support armel-linux-gnueabi.
* Add CMAKE_LIBRARY_ARCHITECTURE_REGEX on kFreeBSD.
* Add CMAKE_LIBRARY_ARCHITECTURE_REGEX on GNU (Hurd).
Also regex is improved to support quadlets. Even if I have not seen this
in the wild yet, reportedly they are possible.
When add_test(NAME) is called without the CONFIGURATIONS argument then
the test is intended to run in any configuration. In multi-config
generators like the VS IDE and Xcode tests created by add_test(NAME) can
only be run when testing a known configuration (otherwise there is no
way to generate the test command line). If no test command line is
known for a particular configuration, or if no configuration is given to
ctest, report the test as not run instead of silently skipping it.
Also fix CMake's own TestsWorkingDirectory test invocation to correct a
previously silent failure exposed by this change.
