ENH: Further refinement of the CPack components functionality from Doug Gregor. Details: ========== - 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)
