Since commit v3.3.0-rc1~397^2 (Check*CompilerFlag: Refactor method used
to pass flags, 2015-02-24) these check modules pass the flags to the
compiler front-end during linking as well as during compilation. This
breaks checks for flags like '-x c++' that are meant only for the
compilation step. Revert the change and add a test covering a
compiler-only flag.

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).
Address the test case
cmake_minimum_required(VERSION 2.8)
set(Python_ADDITIONAL_VERSIONS 3.4 3.5 3.6)
find_package(PythonLibs 3 REQUIRED)
with a Python 3.4.x .pkg installed from python.org on OSX.
Temporarily set CMAKE_FIND_FRAMEWORK to LAST to avoid finding the
system Python.h prematurely.
Add directories inside the frameworks to the search list for the library
as is done for the header.
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.
This was added without explanation by commit v2.8.2~1138 (Add initial XL
C compiler flags for safer builds, 2009-09-30). It is not consistent
with our default C++ flags for XL and disables several optimizations, so
drop it from our default flags for C.

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.

Move the Ld invocation match expression from CMakeDetermineCompilerId
into CMakeDetermine{C,CXX,Fortran}Compiler so that it can be specified
on a per-language basis.
Replace caret-headers with double-quote-headers and replace dash-headers
with caret-headers. This makes the headers match their level of nesting
according to our documentation style guide in cmake-developers(7).
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.
When constructing the "id_src" value for substitution into VS or Xcode
compiler id projects, the input "src" variable already contains the file
name with no path so we do not need get_filename_component. We know
this because CMAKE_DETERMINE_COMPILER_ID_WRITE already references
"${src}" with this assumption.

At least some versions (e.g. C++ Builder 5) of the bcc32 linker are known to
write temporary files with a constant name to the current directory (e.g.
"turboc.$ln"). (This can be verified by using Process Monitor to watch the
file writes that bcc32 / ilink32 / implib make). This causes problems with
some generators that keep a constant current directory and run concurrent
linkers.
For example, the Ninja generator, by default, always has the current directory
set to the top of the build tree - resulting in conflicts between the linkers
that are simultaneously trying to write to "turboc.$ln". Symptoms include
direct errors regarding the "turboc.$ln" file, or later build steps failing due
to corrupted output from previous links that happened to link "successfully."
This is not a problem for the Borland Makefiles generator which does not
run jobs in parallel. For the Ninja generator, work around this problem
by using a link job pool of size 1.
The Concurrent Fortran compiler (ccur.com) is available on Linux and can
be used much like the GNU Fortran compiler. Currently it has no
preprocessor symbols to identify it so we need to detect it by matching
compiler output.

Some compilers can only be distinguished by their compilation output
rather than preprocessor symbols or special flags. Add infrastructure
to determine the compiler id by matching output.
Callers of CMAKE_DETERMINE_COMPILER_ID initialize the
CMAKE_${lang}_COMPILER_ID to unset so we can check it at the end of each
loop iteration instead of the beginning. This approach allows us to
break out of the loop as soon as we succeed. It will also allow checks
to be added in more places within the loop later.
Teach CMAKE_DETERMINE_COMPILER_ID to optionally try detecting the
compiler id using some given flags before trying to detect it with no
special flags. This will be useful for Fortran detection to distinguish
some compilers that use the preprocessors of others but have no macro of
their own by getting verbose output.
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.
Otherwise using a "cc -> ccache" or similar symlink as the compiler
causes FindCUDA to select ccache as the host compiler. Update the logic
added by commit v3.1.0-rc1~354^2 (FindCUDA: Fix OSX Clang & no C
language enabled, 2014-06-12) to apply only in the specific case it is
needed.
Revert commit v3.3.0-rc1~435^2 (Windows-GNU: Do not tell find_library to
treat '.dll' as linkable, 2015-02-18). MinGW tools support linking to
'.dll' files directly and many non-CMake build systems still do not
provide a separate '.dll.a' file.
