Previously only the CMAKE_{C,CXX}_FLAGS_<CONFIG> flags were inspected
for relevant flags when compiling the intermediate link file. We need
to also consider the configuration agnostic flags, CMAKE_{C,CXX}_FLAGS
as well.
AppleClang does not support the cxx_thread_local feature, even
though it is based on a Clang version which does support the
feature.
http://stackoverflow.com/a/23850891/2428389
A possible reason for that is that thread_local might be used as
a variable in existing Apple SDK headers.
Extend the WriteCompilerDetectionHeader module to generate a define
for that feature with portability fallbacks. For the avoidance of
making it easy to write code which looks correct but which has odd
runtime behavior, don't set the define symbol at all if no
equivalent keyword is known.
The SunPro Fortran compiler uses "-F" instead of "-E" to request
preprocessing. The output does not go to stdout so use "-o" to
specify the output file.
This fixes the guess originally made by commit b6b37e30 (Makefile: Add
assembly and preprocessed targets for Fortran, 2014-11-05).

If this option is enabled, the test step is created with the
EXCLUDE_FROM_MAIN option, and if TEST_BEFORE_INSTALL is enabled, the
install step does not depend on the test step.
This means that the test step is never executed, unless the test target
is explicitly created by calling ExternalProject_Add_StepTarget, or by
passing it with the STEP_TARGETS option, or with the EP_STEP_TARGETS
directory property.

When compiling the ABI detection test project, do not override
CMAKE_EXE_LINKER_FLAGS completely. The normally selected value of this
variable may influence how the link is done and may be needed to be
representative of how the calling project will be built. Instead pass a
variable that try_compile will reference as additional flags. Leave
this behavior of try_compile undocumented for now.
Revert the feature added by commit v3.1.0-rc1~420^2~2 (FindOpenGL:
Provide imported targets for GL and GLU, 2014-05-31). Unfortunately it
does not work on Windows because the full path to each library file is
not actually known. The IMPORTED_LOCATION of an imported target must be
a full path, but OPENGL_gl_LIBRARY is just 'opengl32' on Windows because
the actual library file is in some implicit link directory that we may
know know.
More infrastructure will be needed in CMake to allow a name-only
imported library. Until that exists, we will not be able to provide
imported targets in FindOpenGL.
In commit v3.1.0-rc1~640^2~5 (Clean up usage of if(... MATCHES regex)
followed string(REGEX REPLACE regex), 2014-04-06) we accidentally broke
logging of the implicit library detection. Restore use of the
intermediate 'lib' variable so that the log message is constructed
properly.

In commit 079e8469ab (... OpenGL always needs X11 on Unix, 2002-09-05)
the FindOpenGL module was taught to search for X11 as a dependency of
the OpenGL library. This was done without a detailed explanation, and
the dependency should not be explicitly needed because OpenGL headers
should not expose applications to X11 APIs directly.
Unfortunately the only way to know if anything legitimately depends on
this behavior (perhaps in static library cases) is to simply remove it
and wait for issues to be reported. If so, then we can add some kind of
compatibility setting for this later. Add a release note to draw
attention to this change.

Some applications only need the OpenSSL crypto library and want to avoid

Since commit b22e2de8 (HPUX support, 2001-11-05) the FindCurses
module searches for a 'cur_colr' library, but that is not needed
anymore. AFAICT, the cur_colr package was introduced in HP-UX 10.00 and
marked as deprecated in 10.30 by X/OPEN curses (which replaced the even
older HP curses in 10.10).
In order to use cur_colr after 10.10 you should use the
/usr/include/curses_colr when compiling. Since FindCurses doesn't even
search that path the headers cannot possibly match out of the box. If
users want cur_colr they can set the cache entries by hand.
There is no 64-bit version of cur_colr in 11.11PA and it will be gone
completely in 11.31PA:
http://h21007.www2.hp.com/portal/download/files/unprot/STK/HPUX_STK/impacts/i964.html
It is simplest to drop cur_colr support from FindCurses since it was
only partially implemented anyway.

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

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

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.

When using CMAKE_FIND_ROOT_PATH, FindBoost is able to find the first

that, when looking for the other components, Boost_LIBRARY_DIR was
re-rooted against CMAKE_FIND_ROOT_PATH even though it was already a path
on the host. This change fixes this by disabling the re-rooting in the
find_library call when using Boost_LIBRARY_DIR as a hint.

The iOS product type 'com.apple.package-type.bundle.unit-test' requires
code signing on Xcode 6. Other iOS target types do too. Until CMake
learns to add the CODE_SIGN_IDENTITY build attribute itself, toolchain
files can set CMAKE_XCODE_ATTRIBUTE_CODE_SIGN_IDENTITY to tell the Xcode
generator to add the attribute. Teach CMakeDetermineCompilerId to
recognize this variable and add the CODE_SIGN_IDENTITY build attribute
to the compiler id project.
Since commit 0cce556b (Xcode: Use sysroot and deployment target to
identify compiler, 2014-04-29) our compiler id detection project uses
the target platform SDK in case Xcode selects a different compiler based
on it. Now the compiler id project actually compiles with the target
compiler and SDK when cross-compiling.
The iOS tools do not support the 'com.apple.product-type.tool' product
type we use in our compiler id detection project. When targeting
iPhone, use product type 'com.apple.product-type.bundle.unit-test'
instead.
