Teach ExternalProject_Add a new BUILD_ALWAYS option to skip using
the build step stamp file and execute the step on every build.
Extend the BuildDepends test with a case to cover this option.
In Tests/Architecture and Tests/BuildDepends/Project we select a set of
OS X cpu architectures to use for the test. Prior to Xcode 4 we always
used i386 and ppc. Starting with Xcode 4, the tools do not support ppc
but do support x86_64, so we switch to that. Fix the version check to
recognize Xcode >= 5 as at least Xcode 4 and use the new architectures.
Build a shared library and an executable linking to it inside the inner
test. Set LINK_DEPENDS_NO_SHARED on the executable. Add a custom
target to compare the output file times. Verify that on the first build
the executable is newer than the library. Then modify a library source
file. Verify that on the second build the library is newer because the
executable did not have a dependency to re-link.
The code handling IMPLICIT_DEPENDS was only able to track a single file,
the latest file replaced earlier files in the list.
The documentation now mentions that the language has to be prefixed to
every file and the test now uses two implicit dependencies, where only
the second is modified to trigger re-running of the custom command.

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
ppc tools are no longer available in the Xcode 4 installation.
Eliminate the use of the hard-coded 'ppc' in the test when
running on Snow Leopard or later.
- Tests IMPLICIT_DEPENDS_INCLUDE_TRANSFORM properties.
- See issue #6648.
- Works without help in VS IDEs due to native dependency handling.
- Xcode needs help to rebuild correctly.
