Rolf Eike Beer add8d22acc properly detect processor architecture on Windows
CMake is usually run as a 32 bit process even on 64 bit Windows, so the
PROCESSOR_ARCHITECTURE environment variable would always return x86. This post
gives a description on how to do it properly:

Patrick Gansterer 40c36c9f7b VS: Make DetermineCompilerId working with WinCE too
Add a dummy mainCRTStartup() function, since the linker searches for
it instead of main() and set the CMAKE_SYSTEM_* variables depending
on the MSVC_C_ARCHITECTURE_ID and CMAKE_VS_WINCE_VERSION variables.

Brad King 7195aca54f Make platform information files specific to the CMake version
At the top of a build tree we configure inside the CMakeFiles directory
files such as "CMakeSystem.cmake" and "CMake<lang>Compiler.cmake" to
save information detected about the system and compilers in use.  The
method of detection and the exact results store varies across CMake
versions as things improve.  This leads to problems when loading files
configured by a different version of CMake.  Previously we ignored such
existing files only if the major.minor part of the CMake version
component changed, and depended on the CMakeCache.txt to tell us the
last version of CMake that wrote the files.  This led to problems if the
user deletes the CMakeCache.txt or we add required information to the
files in a patch-level release of CMake (still a "feature point" release
by modern CMake versioning convention).

Ensure that we always have version-consistent platform information files
by storing them in a subdirectory named with the CMake version.  Every
version of CMake will do its own system and compiler identification
checks even when a build tree has already been configured by another
version of CMake.  Stored results will not clobber those from other
versions of CMake which may be run again on the same tree in the future.
Loaded results will match what the system and language modules expect.

Rename the undocumented variable CMAKE_PLATFORM_ROOT_BIN to
CMAKE_PLATFORM_INFO_DIR to clarify its purpose.  The new variable points
at the version-specific directory while the old variable did not.

Kitware Robot 9db3116226 Remove CMake-language block-end command arguments
Ancient versions of CMake required else(), endif(), and similar block
termination commands to have arguments matching the command starting the
block.  This is no longer the preferred style.

Run the following shell code:

for c in else endif endforeach endfunction endmacro endwhile; do
    echo 's/\b'"$c"'\(\s*\)(.\+)/'"$c"'\1()/'
done >convert.sed &&
git ls-files -z -- bootstrap '*.cmake' '*.cmake.in' '*CMakeLists.txt' |
egrep -z -v '^(Utilities/cm|Source/kwsys/)' |
egrep -z -v 'Tests/CMakeTests/While-Endwhile-' |
xargs -0 sed -i -f convert.sed &&
rm convert.sed

Kitware Robot 77543bde41 Convert CMake-language commands to lower case
Ancient CMake versions required upper-case commands.  Later command
names became case-insensitive.  Now the preferred style is lower-case.

Run the following shell code:

cmake --help-command-list |
grep -v "cmake version" |
while read c; do
    echo 's/\b'"$(echo $c | tr '[:lower:]' '[:upper:]')"'\(\s*\)(/'"$c"'\1(/g'
done >convert.sed &&
git ls-files -z -- bootstrap '*.cmake' '*.cmake.in' '*CMakeLists.txt' |
egrep -z -v '^(Utilities/cm|Source/kwsys/)' |
xargs -0 sed -i -f convert.sed &&

Kitware Robot 7bbaa4283d Remove trailing whitespace from most CMake and C/C++ code
Our Git commit hooks disallow modification or addition of lines with
trailing whitespace.  Wipe out all remnants of trailing whitespace
everywhere except third-party code.

 '*.c' '*.cmake' '*.cpp' '*.cxx' \
 '*.el' '*.f' '*.f90' '*.h' '*.in' '*.in.l' '*.java' \

Brad King 0bfabf967f OpenBSD: Use 'arch -s' for host processor (#12143)
On OpenBSD 'uname -p' returns a long descriptive name for the processor.
Use 'arch -s' instead to get a short cpu name.

Yaakov Selkowitz 2412d9bc0e Use 'uname -m' for processor on Cygwin (#10774)
POSIX requires 'uname -m' but not 'uname -p':

  http://www.opengroup.org/onlinepubs/9699919799/utilities/uname.html

Indeed Cygwin 'uname -p' returns "unknown".

Brad King 451d68b7e3 Support GNU/kFreeBSD
GNU/kFreeBSD = FreeBSD kernel + userspace with glibc.  Linux.cmake
doesn't contain anything too OS specific, so we can forward to it.

Here are outputs of /bin/uname on author's machine:
  uname -p ==> i386
  uname -o ==> GNU/kFreeBSD
  uname -s ==> GNU/kFreeBSD
  uname -r ==> 5.4-1-686

Patch from Modestas Vainius.  See issue #9659.

Brad King 3a666595c9 Convert CMake non-find modules to BSD License
This adds copyright/license notification blocks CMake's non-find
modules.  Most of the modules had no notices at all.  Some had notices
referring to the BSD license already.  This commit normalizes existing
notices and adds missing notices.

Alexander Neundorf b100fe1fe1 STYLE: don't use an extra file to generate CMakeSystem.cmake but instead
configure the toolchain file into it if required

Alexander Neundorf 512e0d40ef ENH: set UNIX, WIN32 and APPLE in cmMakefile.cxx as it was before, so it
works for scripts, then reset them in CMakeSystemSpecificInformation.cxx, so
the platform modules can set them again for the target system

Alexander Neundorf 176fe63d15 ENH: UNIX, CYGWIN, WIN32, APPLE, QNXNTO and BEOS are not longer set in
cmMakefile.cxx, but now in the platform files and are now valid for the
target platform, not the host platform.
New variables CMAKE_HOST_WIN32, CMAKE_HOST_UNIX, CMAKE_HOST_APPLE and
CMAKE_HOST_CYGWIN have been added in cmMakefile.cxx (...and have now to be
used in all cmake files which are executed before
CMakeSystemSpecificInformation.cmake is loaded). For compatibility the old
set is set to the new one in CMakeDetermineSystem.cmake and reset before the
system platform files are loaded, so custom language or compiler modules
which use these should still work.

Alexander Neundorf 8a6e2bb81d ENH: determine the current system also in cpack, so the search paths are
loaded
Additionally the makefile in cmCPackGenericGenerator is now protected
instead of private, so with these two changes the cpack generators should
now be able to find their tools and how to call these tools from cmake
scripts, instead of hardcoding the search order and command line (as done
e.g. in cmCPackZIPGenerator.cxx)

Alexander Neundorf 6e2fd2c2ca BUG: now the toolchain file is configured into the buildtree, otherwise e.g.
CMAKE_SOURCE_DIR can't be used there
ENH: modify CMakeCCompilerId.c and .h so that sdcc can compile them. As they
were the preprocessor produced:

 9 "test.c"
static char const info_compiler[] = "INFO:compiler["
# 40 "test.c"
""

"]";

and the mixing of the preprocessing directives and the string constants
didn't work.

Alexander Neundorf 61d3444f93 ENH: merge CMake-CrossCompileBasic to HEAD
-add a RESULT_VARIABLE to INCLUDE()
-add CMAKE_TOOLCHAIN_FILE for specifiying your (potentially crosscompiling) toolchain
-have TRY_RUN() complain if you try to use it in crosscompiling mode (which were compiled but cannot run on this system)
-use CMAKE_EXECUTABLE_SUFFIX in TRY_RUN(), probably TRY_RUN won't be able to
run the executables if they have a different suffix because they are
probably crosscompiled, but nevertheless it should be able to find them
-make several cmake variables presettable by the user: CMAKE_C/CXX_COMPILER, CMAKE_C/CXX_OUTPUT_EXTENSION, CMAKE_SYSTEM_NAME, CMAKE_SYSTEM_INFO_FILE
-support prefix for GNU toolchains (arm-elf-gcc, arm-elf-ar, arm-elf-strip etc.)
-move ranlib on OSX from the file command to a command in executed in cmake_install.cmake
-add support for stripping during install in cmake_install.cmake
-split out cl.cmake from Windows-cl.cmake, first (very incomplete) step to support MS crosscompiling tools
-remove stdio.h from the simple C program which checks if the compiler works, since this may not exist for some embedded platforms
-create a new CMakeFindBinUtils.cmake which collects the search fro ar, ranlib, strip, ld, link, install_name_tool and other tools like these
-add support for CMAKE_FIND_ROOT_PATH for all FIND_XXX commands, which is a
list of directories which will be prepended to all search directories, right
now as a cmake variable, turning it into a global cmake property may need
some more work
-remove cmTestTestHandler::TryExecutable(), it's unused
-split cmFileCommand::HandleInstall() into slightly smaller functions
