Features are currently recorded accidentally for all versions of
AppleClang > 3.4 (I have no idea how that relates to upstream
Clang). Presumably that version has the features which are
accidentally recorded, but in the future features will be
recorded initially for only AppleClang >= 5.1, which would
appear as a feature regression.
Commit v3.1.0-rc1~635^2~11 (Don't load Clang-CXX from
AppleClang-CXX., 2013-11-11) ajusted the logic for the CXX
language. Make a similar change for the C language.
Add support for Sun/Uniforum/GNU gettext libintl. This belongs in CMake
rather than upstream because:
* There are multiple upstreams (Sun, GNU).
* It may or may not be in the glibc C library depending
upon the platform and build options used.
Although we already have a FindGettext module, that is for the tools.
This module is for the library, and is independent because it's
perfectly OK to use libintl without the gettext tools (and vice versa),
and they might not all be found. Add cross references between the two
modules in notes to make the relationship clearer.
The change in commit v3.1.0-rc1~85^2 (ExternalProject: Fix download
retry logic, 2014-09-13) dropped the file(DOWNLOAD) EXPECTED_HASH
argument. This prevents file(DOWNLOAD) from skipping the download if
the output file already exists with the proper hash. Restore this check
with explicit code in the download script.

Since commit v3.1.0-rc1~1^2~1 (Xcode: Fix compiler id detection for iOS
tools, 2014-10-22) our compiler id detection project sets the product
type to 'com.apple.product-type.bundle.unit-test'. This causes the Ld
command line on which we match the path to the compiler to have a
'CompilerIdC.xctest/' component. The commit updated our regex to match
this, but placed it before the extra './' component that Xcode 5.0 and
below produce. Xcode <= 5.0 prints '/./CompilerIdC.xctest/', so switch
the order of the two components in the regex to match it.
If UPDATE_DISCONNECTED is set, the update step is not executed
automatically when building the main target. The update step can still
be added as a step target and called manually. This is useful if you
want to allow to build the project when you are disconnected from the
network (you might still need the network for the download step).
This is disabled by default.
The directory property EP_UPDATE_DISCONNECTED can be used to change
the default value for all the external projects in the current
directory and its subdirectories.
Some generators (i.e. Xcode) will not generate a file level target if
no command is set, and therefore the dependencies on this target will
be broken.
This patch sets an empty echo command that does nothing to avoid this
issue.
The ExternalProject_Add_StepDependencies function add some dependencies
for some external project step.
The syntax is:
ExternalProject_Add_Step_Dependencies(<name> <step> [target1 [target2 [...]]])
This function takes care to set both target and file level dependencies,
and will ensure that parallel builds will not break.
It should be used instead of add_dependencies() when adding a dependency
for some of the step targets generated by ExternalProject. See also:
http://thread.gmane.org/gmane.comp.programming.tools.cmake.devel/8680/focus=8926
When adding step targets using ExternalProject_Add_StepTargets, the
STEP_TARGETS argument or the EP_STEP_TARGETS property, ExternalProject
sets all the dependencies for the main project to that target. Due to
this, the update target cannot be used without downloading and building
all the dependencies.
In order to be able to add step targets that do not depend on other
external projects, this patch adds:
* An optional "NO_DEPENDS" argument to the
ExternalProject_Add_StepTargets function. If this argument is set,
then no dependencies are set for the target (file dependencies will
still be set).
* A new argument INDEPENDENT_STEP_TARGETS to the ExternalProject_Add
function and a new directory property EP_INDEPENDENT_STEP_TARGETS that
behave like STEP_TARGETS and EP_STEP_TARGETS, but cause the
ExternalProject_Add_StepTargets to be called with the NO_DEPENDS
argument.

Cleanup of Windows-wcl386.cmake in commit v3.1.0-rc1~693^2 (Watcom:
Cleanup Windows-wcl386 configuration, 2014-04-01) also introduced use of
the 'symfile' link option but did not mention it in the commit message.
There is no way to set the symbol file name of a target, so it is better
to revert that change. It is easy to run 'wstrip *' if the symbols need
to be stripped, but it is very difficult to get the right names for the
.sym files to install with debug/rel_with_deb_info configurations.

36cf8a1e Tests/Tutorial: Fix when USE_MYMATH is OFF
This argument allows to set default arguments that are written in the
initial cache file, but that are not forced, and therefore allows the
user to change these values later (CMAKE_ARGS and CMAKE_CACHE_ARGS
always overwrite the values).
Also add some documentation to explain the differences between these 3
arguments.
Extend ExternalProjectLocal test to cover CMAKE_CACHE_DEFAULT_ARGS.
With CMAKE_C_COMPILER=clang and CMAKE_C_FLAGS='-Wall -Werror', this test
breaks with -Werror,-Wuninitialized. Fix this by getting rid of the
temporary variable.
