- 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.

==========
- New cpack_add_component, cpack_add_component_group, and
cpack_add_install_type "commands" defined as macros in the CPack
module.
- Documentation for all of the variables and commands in the CPack module.
- Added get_cmake_property(... COMPONENTS) to CMake to ask for the
names of all components. Used in the CPack module to automatically
build component-based installers. (Set CPACK_MONOLITHIC_INSTALL to
turn off component-based installation).
- A group can declare its PARENT_GROUP, to build an arbitrary
hierarchy of groups.
- New CPack command cpack_configure_downloads, which creates an
installer that downloads only the selected components on-the-fly.
Those components marked DOWNLOADED will be separate packages
downloaded on-the-fly (or, all packages can be marked as such with the
ALL option to cpack_configure_downloads). Individual components are
compressed with ZIP at installer-creation time and
downloaded/uncompressed by the installer as needed. This feature is
only available on Windows with NSIS at the moment.
- NSIS installers can install themselves and enable the "Change"
button in Add/Remove programs, allowing users to go back and install
or remove components. This can be disabled through
cpack_configure_downloads, because it's only really useful is most of
the application's functionality is in downloaded components.
- Bug fix: automatically install everything whose COMPONENT was not
specified (it's a hidden, required group)
- Bug fix: fixed removal of components when re-running the NSIS
installer and unchecking components
- Bug fix: NSIS installers now only install/remove the minimal
number of files when re-run to update the installation (or by clicking
"Change" in Add/Remove programs)
