Since commit v2.4.0~4325 (...use gcc -shared, even for C++ libraries,
2003-03-13) we use the C compiler "gcc" to link C++ shared libraries
compiled with "g++". At the time "g++" did not know how to link shared
libraries correctly. This has long since been fixed so simply drop the
special case.
Since commit v3.1.0-rc1~564^2 (OS X: Use -iframework for system
framework directories, 2014-05-05) we test the version of Clang to see
if it supports -iframework. Fix the version test used for AppleClang
since it uses a different version scheme than upstream Clang.
Run our check for the '_' prefix using a bzip2 API function as declared
with a prototype in the real header file. This is needed in case the
function is provided in a DLL import library where the symbol name may
not match without proper markup from the header.
If someone in KDE wants to port away from OLD policies, they might want to do
so one policy at a time. This patch will allow them to use
find_package(KDE4 NO_POLICY_SCOPE)
in callers to get around the CMP0011 warning, while still getting the policy
settings contained within.
The module is not needed anymore for try_compile or try_run. It cannot
be used with CMP0022 NEW behavior due to generator expressions in
INTERFACE_LINK_LIBRARIES, so document it as deprecated. Whatever
problems other than try_compile and try_run anyone tried to solve with
this module will have to be addressed another way.

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.

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).

This was added without explanation by commit v2.8.2~1138 (Add initial XL

Replace caret-headers with double-quote-headers and replace dash-headers

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.
In commit v3.3.0-rc1~132^2 (FindwxWidgets: Search for wx-config-3.0 in
addition to wx-config, 2015-04-29) we added a second (versioned) name to
the find_program call. Specifying multiple names requires use of the
NAMES option. Add it now. While at it, also add versioned names for
2.9 and 2.8.
Check for this flag explicitly in the --help output before using it. It
turns out there are some versions of the tool that support --version but
not --ignore-missing-info.
Honor the GIT_SUBMODULES option added by commit v3.0.0-rc1~92^2
(ExternalProject: Add option GIT_SUBMODULES, 2014-01-09) during the
'git submodule init' step to avoid initalizing all modules since we
are only going to update the specified subset anyway. This will
be useful for project repositories that have many submodules
(e.g. https://github.com/boostorg/boost).

On Ubuntu/Debian, starting with PostgreSQL 9.3 the header file pg_type.h
is moved to a separate package (from libpq-dev to postgresql-server-dev)
and consequently the file pg_type.h is moved to a new location:
/usr/include/postgresql/<version>/server/catalog/pg_type.h
While at it, use separate PATH_SUFFIXES variables for library, type and
include (this is merely an optimization).
These cache entries introduced by commit 892b854f (FindBoost: Search for
debug and release libraries separately, 2015-01-26) should be marked as
advanced just as Boost_LIBRARY_DIR was. Also their _LAST values should

handled by code looking in _Boost_VARS_LIB for a list of relevant
variables. Fix construction of this list that was broken by the above

Do not force a specific policy version in the module because it prevents
projects from setting newer policies to NEW. In particular, projects
may want to set CMP0056 to NEW to affect any try_compile calls in this
module.

2.8.0 behavior, 2009-11-17) in order to set CMP0007 to NEW. Simply set
