Allow the `Swift` language to be enabled with the Xcode generator for
Xcode >= 6.1. Reject it on other generators and with older Xcode
versions. Since Apple is the only vendor implementing the language
right now, the compiler id can be just `Apple`.
Added new USES_TERMINAL option to the ExternalProject_Add_Step
function. This option passes USES_TERMINAL to the underlying
add_custom_command call so that the Ninja console pool is used.
Also, corresponding new USES_TERMINAL_<step> options were added
to the ExternalProject_Add function.
Justification: if using Ninja with a CMake superbuild, it's often
desirable to limit the superbuild to ONE sub-Ninja process at a
time to avoid oversubscribing the CPU. Using the console pool also
makes it easy to monitor the progress of the sub-Ninja process.
Independent USES_TERMINAL_<step> arguments are passed to
ExternalProject_Add instead of one USES_TERMINAL argument that
controls everything. Users may wish to run some steps in parallel
but not others (e.g. parallelize configure but not build).
Create target property WINDOWS_EXPORT_ALL_SYMBOLS to automatically
generate a module definition file from MS-compatible .obj files and give
it to the linker in order to export all symbols from the .dll part of a
SHARED library.
In commit v3.3.0-rc1~352^2~3 (Genex: Allow COMPILE_LANGUAGE when
processing compile definitions, 2015-03-04) the name of the variable
used to pass preprocessor definitions to the Fortran dependency scanner
was changed to be per-language, but the actual dependency scanning code
was not updated accordingly. Update the code and add a test case.

Add a TestLoad setting to CTest that can be set via a new --test-load
command-line option, CTEST_TEST_LOAD variable, or TEST_LOAD option to
the ctest_test command. Teach cmCTestMultiProcessHandler to measure
the CPU load and avoid starting tests that may take more than the
spare load currently available. The expression
<current_load> + <test_processors> <= <max-load>
must be true to start a new test.

If a Windows resource (.rc) source file is included in a STATIC library,
the VS "link" tool will process the compiled ".res" file and needs to know
the target architecture. Without it, we may get a LNK4068 warning and
possibly a LNK1112 error. Add /machine: to the default static library
flags to give the link tool the information it needs.
Since commit v3.3.0-rc1~62^2~5 (cmTarget: Store only cmListFileContext
for CMP0023 handling, 2015-05-18) a call to target_link_libraries on a
target that was defined in another (non-ancestor) directory crashes
because no execution context is left active. Fix this by getting the
execution context from the actual cmMakefile where the current
target_link_libraries call takes place. Test this by verifying that
such calls correctly produce an error diagnostic instead of crashing.
When writing export files, correctly encode property values that contain
characters special to the CMake language parser. We must ensure that
they parse correctly when loaded on the consuming side.

The fix in commit v3.2.3~3^2 (Fix assertion failure on unmatched foreach
in function, 2015-05-18) broke handling of unmatched non-loop blocks
because it assumed all function blockers removed during error unwinding
were for loops, essentially switching the set of mishandled cases.
The purpose of the loop block push/pop operations is to define a scope
matching the lifetime of the loop function blockers. Since our function
blockers already have the proper lifetime, simply move the push/pop
operations to their constructor/destructor.
Extend the RunCMake.Syntax test with a case covering this.
Since Qt 5.4.2, it is necessary to compile against Qt 5 with -fPIC
and not -fPIE when using GCC 5. Not doing so results in a hanging
test in this case, so use the PIC flag directly instead.
In commit v3.2.0-rc1~480^2 (QtAutogen: Regenerate qrc files if their input
changes, 2014-09-17) the "cmake -E cmake_autogen" rule was switched from
always running to running as a custom command with dependencies if rcc
is enabled. This is not correct because automoc always needs to re-run.
Switch back to always running the command.
8bcec4d2 Help: Add notes for topic 'GNUInstallDirs-special-prefixes'
c8bd37ec GNUInstallDirs: Add special cases for certain prefixes
5f30f175 GNUInstallDirs: Add test cases
Teach the module to handle SYSCONFDIR and LOCALSTATEDIR properly if
CMAKE_INSTALL_PREFIX is set to `/` or `/usr` -- i.e. as expected by GNU
Coding Standard (i.e. set SYSCONFDIR to `/etc` and `LOCALSTATEDIR` to
`/var`). Also if CMAKE_INSTALL_PREFIX is set to /opt/pkg, `SYSCONFDIR`
must be set to `/etc/opt/pkg` and `LOCALSTATEDIR` to `/var/opt/pkg`
according to FHS.
Add a RunCMake.GNUInstallDirs test with cases covering various install
prefixes. Hard-code the architecture information. Tolerate all
platform-specific LIBDIR values.
Currently the root prefix is not handled well, but verify the current
behavior in the test anyway. This can be addressed with a future
change.

Move PARTIALLY_RELOCATABLE_WARNING test to the new common CPack test
script structure to have all tests in one place as well as additional
benefit of having some more checks done during test execution.
Create a <LANG>_COMPILER_LAUNCHER target property (initialized by a
CMAKE_<LANG>_COMPILER_LAUNCHER variable) to specify a compiler launcher
tool. This will supersede the CMAKE_<LANG>_COMPILER_ARG1 approach to
using such tools. The old approach set CMAKE_<LANG>_COMPILER to the
launcher tool while the new approach leaves this variable set to the
actual compiler.
Implement this property for Makefile and Ninja generators. It cannot be
implemented for VS or Xcode generators as the IDE build tools offer no
such hooks.
The VS >= 10 generators need to parse the .sln file from the build
directory to locate targets in subdirectories. This occurs after we
change the working directory to the build tree. If a relative directory
other than "." was given then we would change to it and also refer to
the .sln file location with it. Fix this by converting the build tree
to a full path always. This will also give a more informative error
message when the directory does not exist.
Make RETURN_VALUE report -1 if the update command failed as the
documentation claims. Also avoid reporting a ctest script-level failure
if the update command fails because we still correctly administered the
update step.
Use the KWSys Process "MergeOutput" option to give each test child
process the same pipe for both stdout and stderr. This allows natural
merging of stdout and stderr together instead of merging on arbitrary
buffered read boundaries as before.
The CMAKE_FRAMEWORK_PATH and CMAKE_APPBUNDLE_PATH cache variables are
supposed to be used to generate the extra paths passed to pkg-config,
but instead the CMAKE_PREFIX_PATH variable is used.
This bug was introduced by the refactor in commit v3.1.0-rc1~747^2~1.
The <LANG>_VISIBILITY_PRESET and VISIBILITY_INLINES_HIDDEN were first
merged in commit v2.8.12~322 (Merge topic 'VISIBILITY_PRESET-property',
2013-06-05) but worked only for shared libraries and executables with
exports. Prior to commit v3.0.0-rc1~581^2 (GenerateExportHeader:
Deprecate add_compiler_export_flags function., 2013-09-02) the
add_compiler_export_flags function was used to add visibility flags to
all targets.
The visibility flags are useful for sources in all target types because
they may be later linked into shared libraries or executables with
exports. Introduce policy CMP0063 to enable them for all target types
while preserving compatibility with existing projects that do not expect
this.
Enable languages only in the individual test case. Enable the test
everywhere except Visual Studio generators (which do not implement the
properties) and just set fake flags as needed to activate relevant code
paths. Drop unneeded CMAKE_SUPPRESS_REGENERATION which seems to have
been copied from an unrelated test when this test was created.
