Subject: ENH: Give Mac installers package relocation capability. Default
 location is still the same for backwards compatibility, but packages will now
 be relocatable by default like they are on Windows via the NSIS installer.
 New CPack variables for controlling this functionality are
 CPACK_PACKAGE_DEFAULT_LOCATION and CPACK_PACKAGE_RELOCATABLE.
