Brad King 58b2d760ee Modules: Format documentation to avoid over-long preformatted lines
Convert several preformatted code block literals that enumerate lists of
options or variables to use reST definition lists instead.  Manually
wrap other long lines in code blocks.

Kitware Robot f051814ed0 Convert builtin help to reStructuredText source files
Run the convert-help.bash script to convert documentation:

 ./convert-help.bash "/path/to/CMake-build/bin"

Then remove it.

Brad King a0a0877a1e OS X: Always generate -isysroot if any SDK is in use
Drop the last use of CMAKE_OSX_SYSROOT_DEFAULT.  Replace internal
platform variable CMAKE_${lang}_HAS_ISYSROOT with a more general
CMAKE_${lang}_SYSROOT_FLAG variable.  If the -isysroot flag exists and
CMAKE_OSX_SYSROOT points to an SDK (not "/") then always add it to
compiler command lines.  This is already done in the Xcode IDE.

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

Yury G. Kudryashov 0b8638821e CMakeFindPackageMode: fix 32/64bit detection if 'file' is a symlink 2012-02-28 12:59:01 -05:00
Alex Neundorf 59238dc2de Fix --find-package mode on Cygwin, where enable_language(RC) is called
In --find-package mode we can't enable a language, since a lot of
stuff has not been set up, e.g. which make tool to use.
So disable enable_language() in this mode.

Alex Neundorf 98472e45c8 Require the current cmake version in --find-package mode
This fixes the problem that otherwise Platforms/CYGWIN.cmake doesn't
know whether it should set WIN32 or not.
Now it uses always the current behaviour.

Alex Neundorf e589589ab1 Rename helper macros print_compile_flags() to set_compile_flags_var()
The same for print_link_flags(), it is now set_link_flags_var().
Both macros don't print anything anymore, this was only in the
beginning.

Alex Neundorf 53edfb206b Better support for lib64 and Debian multiarch
If CMAKE_SIZEOF_VOID_P is not set from the outside, it checks for the
existance of /usr/lib64, and if it exists, SIZEOF_VOID_P is set to 8.

For multiarch, if this is debian and
CMAKE_${LANGUAGE}_LANGUAGE_ARCHITECTURE has not been set, it globs
for the files in /lib, and uses the first one which matches
CMAKE_LIBRARY_ARCHITECTURE_REGEX.

Alex Neundorf e4f603b698 Implement find-package mode of cmake
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
