This change introduces policy CMP0008 to decide how to treat full path
libraries that do not appear to be valid library file names. Such
libraries worked by accident in the VS IDE and Xcode generators with
CMake 2.4 and below. We support them in CMake 2.6 by introducing this
policy. See policy documentation added by this change for details.
Sometimes we ask the linker to search for a library for which the path
is known but for some reason cannot be specified by full path. In these
cases do not include the library in CMP0003 warnings because we know the
extra paths are not needed for it.
- Find newer additions such as animate, compare, etc.
- Find development api: Magick++, MagickCore, MagickWand
- Use FindPackageHandleStandardArgs to output standard messages.
- This case worked accidentally in CMake 2.4, though not in Makefiles.
- Some projects build only with the VS IDE on windows and have this
mistake.
- Support them when 2.4 compatibility is enabled by adding the extension.
CMAKE[_SYSTEM]_(LIBRARY|PROGRAM|INCLUDE|PREFIX)_PATH variables
-moved CMAKE_CROSSCOMPILING from "Variables that modify behaviour" to
"variables that Provide Information", since it should be used only for
testing whether we are currently in cross compiling mode, not for switching
between the modes.

Older GCC on the Mac warns for use of long double, so we use
-Wno-long-double. Newer GCC on the Mac does not have this flag and
gives an error. We now check for the flag before using it.
See bug #7357.
Utilities/cmcurl/CMake provides macros with the same file names and
macro names as others in Modules, but with different interfaces. We
rename the curl ones to avoid conflict.
- The source-file signature of try_compile looks up the language
of the source file using the extension-to-language map so that
it knows what language to enable in the generated project.
- This map needs to be filled before loading a file specified by
CMAKE_USER_MAKE_RULES_OVERRIDE
CMAKE_USER_MAKE_RULES_OVERRIDE_<LANG>
so that the user file may call the try_compile() source-file
signature.
- It must still be re-filled after loading CMake<LANG>Information.cmake
in case the compiler- or platform-specific files added anything.
- See bug #7340.
- ld flags -dylib_compatibility_version and -dylib_current_version
are libtool flags -compatibility_version and -current_version
- OSX 10.3 does not like the dylib_ prefixes.
