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
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.

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.

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.

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
