I believe there should be no need for a presentation tool to depend on so
many development packages:

Installing:
  pympress

Installing dependencies:
  build-essential  g++-14-i686-linux-gnu  gobject-introspection      libgio-2.0-dev         libglib2.0-dev      libpcre2-dev     libsepol-dev              native-architecture
  g++              g++-i686-linux-gnu     gobject-introspection-bin  libgio-2.0-dev-bin     libglib2.0-dev-bin  libpcre2-posix3  libstdc++-14-dev          python3-mako
  g++-14           girepository-tools     libblkid-dev               libgirepository-2.0-0  libmount-dev        libselinux1-dev  libsysprof-capture-4-dev  python3-markupsafe


It seems that they are pulled in via gobject-introspection, which was added
as a dependency in the fix for bug #956840
But gobject-introspection is a development tool and doesn't even contain
the files mentioned as missing in that bug report, so I'm not sure if this
was actually needed.
