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
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.

Teach the Makefile and Ninja generators to substitute for an <INCLUDES>
placeholder instead of putting -I in <FLAGS>. Update our values for
CMAKE_<LANG>_COMPILE_OBJECT,
CMAKE_<LANG>_CREATE_ASSEMBLY_SOURCE, and
CMAKE_<LANG>_CREATE_PREPROCESSED_SOURCE
to place <INCLUDES> just before <FLAGS>.
Update our values for
CMAKE_<LANG>_COMPILE_OBJECT,
CMAKE_<LANG>_CREATE_ASSEMBLY_SOURCE, and
CMAKE_<LANG>_CREATE_PREPROCESSED_SOURCE
to place <DEFINES> before <FLAGS> consistently across supported
compilers. We already do this for most compilers, so update the rest
for consistency.
Extend the workaround added by commit v3.2.0-rc1~278^2 (FindMPI:
Workaround Intel MPI 5.0.1 exit code problem, 2014-12-04) with an
additional/alternate keyword to recognize the case with recent GCCs.
The Apple Clang 6.1 compiler that comes with Xcode 6.3 is aware of the
modern -std=c++14 and -std=gnu++14 flags, so use them instead of the
"1y" flags.

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.
