    cpack: improve source tarball generation by adding the "dist" target.

    The source package must not contain compiled objects. If the build dir
    is under the source tree, it is included too. By excluding /build/ we
    avoid to add every build dir, but if the build dir doesn't contain
    build the problem still persist.
