Since commit v2.8.7~31^2 (HP: Drive shared library linking with compiler
front end, 2011-12-12) the C compiler is used to link shared libraries
instead of calling the linker directly, so linker options need to be
wrapped as -Wl,-foo instead of -foo.
The compiler version reported since commit v2.8.2~1018 (CTest-side
support for compiler name and compiler version, 2009-10-12) only
reported the version of the compiler used to build CMake, and only
if it defined "_COMPILER_VERSION". Instead use the version of
the compiler used to build the project CTest is testing.
By default Mercurial command "clone" will implicitly call "update" with
the "default" branch after downloading the cloned repository. However
ExternalProject_Add() always generates a second "update" command after
cloning with a tag which is either specified or "tip" (equivalent to
"default" by default). Therefore ExternalProject will first clone then
update to default branch then update to another specified branch if
provided. This leads to potentially very long clone operation (in
particular when the repository default branch contain subrepos) which
can lead to transaction abort triggered by the server.
Simply use "hg clone -U" to avoid the implicit update during clone.
Our following call to "hg update" will take care of updating anyway.
Protobuf 2.6.x and lower do not use CMake (cmake is usable in Protobuf
3.x) but provide legacy Visual Studio projects files. Search their
output directories in 64-bit builds.
The Fortran compiler version detection infrastructure added by commit
v3.3.0-rc1~436^2~9 (Fortran: Add infrastructure to detect compiler
version, 2015-02-17) forgot to update CMakeFortranCompiler.cmake.in to
save the compiler version persistently as we do already in
"CMake{C,CXX}Compiler.cmake.in". Add the missing line now.
As dumpbin.exe is no longer reliable for gcc libraries on MinGW because
it crashes on many common libraries like libgcc_s and libgfortran it is
now necessary too resort to using objdump for DLL dependency walking.
Using objdump has a secondary problem in that it generates a lot of
output for large libraries and causes fixup_bundle() to take many
minutes to process what took fractions of a second with
"dumpbin.exe /dependents".
Add a 'grep' pre-filter in the execute_process() command pipeline to
reduce this output to a minimum for a several orders of magnitude speed
up. If grep is not available just use the full output.
As there does not seem to be a reliable way of detecting MinGW, callers
of fixup_bundle() may have to set the variable gp_tool to "objdump" if
dumpbin.exe is installed on the build machine to stop it using the
broken MS dumpbin.exe for library dependency walking.
Since commit v2.8.5~121^2~2 (FindMPI: Handle multiple languages,
2010-12-29) we called the GetPrerequisites is_file_executable function
but passed the name of a CMake variable instead of its value. Therefore
the function has always failed and caused the search for the compiler
name to run even with an absolute path. Switch to using if(IS_ABSOLUTE)
instead and drop use of GetPrerequisites.
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

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)

The module is not needed anymore for try_compile or try_run. It cannot

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

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).

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

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

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

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).
