Apple distributes their own Clang build with their own version numbers
that differ from upstream Clang. Use the __apple_build_version__ symbol
to identify the Apple Clang compiler and report the Apple Build Version
as the fourth version component in CMAKE_<LANG>_COMPILER_VERSION. Add
Compiler/AppleClang-<lang> and Platform/Darwin-AppleClang-<lang> modules
that simply include the upstream equivalents.
Fix comparisons of CMAKE_<LANG>_COMPILER_ID to Clang in CMake's own
source and tests to account for AppleClang.
5f11b8d Eclipse: add version 4.3 for completeness
2b63734 Eclipse: print different message if CMAKE_ECLIPSE_VERSION is already set
1ff8c21 CMakeFindEclipse: use lowercase for macro calls
Teach the compiler identification preprocessor tests to report when
Clang simulates MSVC, and what version. If not MSVC, assume GNU.
Teach compiler information modules Clang-(C|CXX) to recognize when Clang
simulates MSVC and skip loading the GNU information.
Teach the Windows-MSVC platform information to recognize when it is
loaded as the simulated compiler and use that version information
instead of the real compiler's (different) version scheme.
Add platform modules Windows-Clang-(C|CXX) and support module
Windows-Clang to load either Windows-MSVC or Windows-GNU and wrap
the corresponding information macros.
Some compilers try to simulate other compilers as a drop-in replacement
supporting all the same command-line options and predefined preprocessor
macros. In such cases it will be useful to have CMake load the compiler
information files for the simulated compiler instead of duplicating the
information. Teach CMakeDetermineCompilerId to extract the simulated
compiler id and version when the compiler id detection provides it.
In Modules/Platform/Darwin.cmake set CMAKE_SYSTEM_FRAMEWORK_PATH to
include framework directories from inside the system SDK corresponding
to CMAKE_OSX_SYSROOT.

The subsystem must be set to WINDWOSCE for some SDKs to link an
executable. Set it to 9 for VS2005 and to 8 for VS2008, since the
value differs between the different Visual Studio versions.
In commit bd827f98 (Use COFF file header header for architecture
detection, 2013-08-05) the MSVC_<lang>_ARCHITECTURE_ID value computed by
CMakeDetermineCompilerId.cmake changed for WinCE architectures to be the
exact architecture read from the PE header. Fix platform preprocessor
definitions in Modules/Platform/Windows-MSVC.cmake to correspond to the
architecture family (ARM or SHx) instead of the specific architecture.
In commit 8fcf0ab0 (Add support for new Windows CE compiler, 2013-08-04)
we made corelibc conditional on the MSVC version, but the version value
was incorrect. Update it to use corelibc for VS 2008 and below.
When FindHDF5 was first added in commit e6734068 (Add HDF5 find
module..., 2009-08-24) it contained a workaround for a bug in
SelectLibraryConfigurations that did not transform lists correctly.
That bug was fixed by commit 5797512c (SelectLibraryConfiguration:
generate correct output when input vars are lists, 2012-07-28). Then
refactoring in commit 04d4dc33 (SelectLibraryConfigurations: Use
-NOTFOUND instead of copying the vars, 2013-07-08) changed undocumented
behavior on which the original workaround relied. The result puts
entries like HDF5_hdf5_LIBRARY_DEBUG-NOTFOUND in HDF5_LIBRARIES.
Fix this by dropping the original workaround since the underlying issue
has been fixed anyway. Use the HDF5_${LIB}_LIBRARY selected by the call
to select_library_configurations directly.
In commit 2a797539 (FindPNG: improve library detection, 2013-07-27) we
split the search for PNG into separate PNG_LIBRARY_DEBUG and
PNG_LIBRARY_RELEASE variables. However, if a project or user sets the
old PNG_LIBRARY value we must honor it instead of searching.
While at it, mark PNG_LIBRARY_RELEASE and PNG_LIBRARY_DEBUG as advanced
and remove a stray debug message.
CMake's intended interface for linking to explicit object files (marked
with EXTERNAL_OBJECT) is that only those listed as target sources should
be linked. Drop FindCUDA's attempt to hide the .obj files from VS IDE
project files, which depends on VS-version-specific behavior of linking
custom command outputs that happen to be named "*.obj". CMake puts
external object files in a dedicated source group anyway.
In commit fb9f73de (MSVC: Invoke 'link' directly for executables,
2013-04-08) we forgot to remove the /link option handling added by
commit e31df039 (Ninja: move <OBJECTS> in front of the first linker
option, 2012-09-27) to the Platform/Windows-MSVC module. Drop it now.
When compiling the 64 bit version of wxWidgets using nmake the library
folders become vc_x64_lib and vc_x64_dll and can coexist with the win32
version.
When the VS IDE build output setting
Tools -> Options -> Projects and Solutions ->
Build and Run -> MSBuild project output verbosity
is set to "Diagnostic" the build output contains a " (TaskId:###)"
suffix on the CMAKE_<lang>_COMPILER= line used to extract the compiler
executable location. Strip this suffix before checking that the
reported location exists.
Follow-up to commit 4a015f77 (OpenBSD: Add paths for Tcl/Tk 8.4/8.5,
2012-12-03): those paths added for OpenBSD also work on other BSDs, some
of which are already using version 8.6 of Tcl/Tk.
After building the test binary tell find_program to search for it with
the ${CMAKE_EXECUTABLE_SUFFIX} so that the .exe can be found. Since
find_program is normally used to locate host tools while cross-compiling
it needs this hint to find the target binary.
