[GNC] Boost on Ubuntu 25.10

[Stephen M. Butler]

After upgrading to Ubuntu 25.10 I had to re-install the libboost-all-dev 
package (the upgrade appeared to have removed it) in order to compile 
the latest version of GnC.

Just an FYI to anyone else who locally compiles GnC on a Ubuntu box.

Note:  GnC -- currently working to compile 5.13-36.
             Ubuntu -- 25.10

Attempting to run the prior version of GnC (5.13-9) compiled under 
Ubuntu 25.04 gives:

    gnucash --debug
    gnucash: error while loading shared libraries:
    libboost_program_options.so.1.83.0: cannot open shared object file:
    No such file or directory


Search shows these are on my box after the 25.10 upgrade:

    sudo find / -name libboost_program_options.so*
    /usr/lib/x86_64-linux-gnu/libboost_program_options.so
    /usr/lib/x86_64-linux-gnu/libboost_program_options.so.1.88.0
    /home/steve/snap/thunderbird/common/.thunderbird/iwyj6lvo.default/pepmda/lib/libboost_program_options.so.1.62.0
    /home/steve/.thunderbird/iwyj6lvo.default/pepmda/lib/libboost_program_options.so.1.62.0


The recompile works.
