    There is software called "MeshLab:"

    <https://github.com/cnr-isti-vclab/meshlab>

    I don't want to build it so I downloaded a pre-built tarball.

    The pre-built package contains many libraries that are already
    installed on my system, but the program cannot use my system libraries.
    They will result in errors:

    meshlab: symbol lookup error: meshlab: undefined symbol: _ZdlPvm, version Qt_5

    Thus, I need to use the specific libraries that are distributed
    with the pre-built tarball.

    How can I use these libraries to run MeshLab without removing or
    overwriting the ones that are already on my system?

    If you know GNU/Linux then you will know the answer.

    If you don't know the answer then you do not belong on this
    group. GTFO.

    RTFM: https://man7.org/linux/man-pages/man8/ld.so.8.html hint:
    LD_LIBRARY_PATH

    Short answer for you:
    1. Open console where you have meshlab and Qt *.so lib files;
    2. Run:
    $ export LD_LIBRARY_PATH="$PWD:$LD_LIBRARY_PATH" && ./meshlab
