Peter Kümmel 3a2c8e8e66 Ninja: disable work around when linking with mingw
The work around is only needed by older GCCs (only testet 4.4/4.7)
Ninja is very new so chances are high that there is also a new mingw.

Use slashes in link rsp file, because ar.exe can't handle \.

Stephen Kelly 31d7a0f2e3 Add platform variables for position independent code flags
Store in new platform variables

  CMAKE_${lang}_COMPILE_OPTIONS_PIC
  CMAKE_${lang}_COMPILE_OPTIONS_PIE

flags for position independent code generation.

In almost all cases, this means duplication of the
CMAKE_SHARED_LIBRARY_${lang}_FLAGS for the _PIC case and using the
assumed pie equivalent for the _PIE case.  Note that the GNU compiler
has supported -fPIE since 3.4 and that there is no -fPIC on GNU for
Windows or Cygwin.

There is a possibility that the _PIE variables are not correct.
However, as there is no backwards compatibility to be concerned about
(as the POSITION_INDEPENDENT_CODE property is not used anywhere yet),
the current state suffices.

Brad King c213eb9cbf Windows-GNU: Remove extra quotes in GNUtoMS rule variable
CMake replaces the <TARGET...> tokens with properly quoted values so we
do not need an extra set of quotes around them.

Brad King afb00fef19 Add CMAKE_GNUtoMS option to convert GNU .dll.a to MS .lib
Teach the Windows-GNU.cmake platform file to look for Visual Studio
tools matching the target ABI.  Add an extra step to the link command
for shared libraries and executables that export symbols and on which a
new GNUtoMS property is set (initialized by the CMAKE_GNUtoMS option).
Tell the GNU linker to output a module definition (.def) file listing
exported symbols in addition to the GNU-format import library (.dll.a).
Pass the .def file to the MS "lib" tool to construct a MS-format DLL
import library (.lib).

Teach the install(TARGETS) command to install the MS import library next
to the GNU one.  Teach the install(EXPORT) and export() command to set
the IMPORTED_IMPLIB property pointing at the import library to use the
import library matching the tools in the importing project.

Brad King 86cb17b18d Pass include directories with response files to GNU on Windows
The GNU 4.x toolchain on MinGW (and therefore MSYS) allows compiler
options to be passed via response files.  Use this to pass include
directory -I options.  This allows the include file search path to be
very long despite shell and mingw32-make command line length limits.

Brad King 761621645c Pass .def files directly to MinGW tools (#9997)
Commit 6a61a8a5 (Honor module .def files with MinGW tools, 2011-02-21)
set CMAKE_LINK_DEF_FILE_FLAG to "-Wl," to enable passing .def files to
the linker on MinGW.  However, older GNU tools in the MSYS shell do not
know how to translate "-Wl,/c/..." to "c:/..." and complain that the
file does not exist.  Instead set the flag to just "" which tells CMake
it can pass the file through the front-end with no special flag.

Brad King 6a61a8a538 Honor module .def files with MinGW tools (#9997)
Since commit 024d05ad (Fix use of module .def files for MS tools,
2009-09-29) module .def files work for any platform that sets
CMAKE_LINK_DEF_FILE_FLAG correctly.  Set it in the Windows-GNU platform
information file to enable support with MinGW tools.  Also enable the
test added by commit 0db2c850 (Test use of module .def files for MS
tools, 2009-09-29) for MinGW and MSYS generators.

Brad King 5f05a3c25e MinGW: Support long object file lists
Use a combination of response files and the archiver to support long
object file lists that do not fit in the Windows command-line length
limit.  This can work only with GCC >= 4 because the MinGW GCC 3.x
front-ends do not support response-file syntax.

Brad King b03f4ec09d No response files with GNU ld <= 2.16 (#10913)
Older GNU ld does not support the @FILE syntax for response files.
Check the ld version on MinGW and MSYS before enabling the syntax.

Brad King 00477de1c9 Use response file for objects on MinGW and MSYS
Windows command lines are limited to about 32K so we need to use
response files for linking very large lists of object files.

See issue #10401.

Brad King 4eba05de42 Suppress GNU flag -fPIC on Windows
Commit "Modernize GNU compiler info on Windows" (2009-12-02) reorganized
GNU flags on Windows but let -fPIC slip through for compilation of
objects in shared libraries.  While this flag is valid on most GNU
compiler platforms we need to suppress it in Windows-GNU.cmake just as
we already do in CYGWIN-GNU.cmake.
