Add per-component CPACK_OUTPUT_FILE_PREFIX settings
I'd like to be able to put tarballs of individual components into different directories. Right now it's possible to specify the file name with CPACK_ARCHIVE_<component>_FILE_NAME
. I'd like to be able to use something like CPACK_OUTPUT_<component>_FILE_PREFIX
which takes precedence over CPACK_OUTPUT_FILE_PREFIX
.
