* [`control`](./debian/control) — one source stanza and 18 binary packages (`omc`,
`libomc`, `omedit`, `omshell`, `omnotebook`, `omsimulator`, `omlibrary`, …). Some
build dependencies carry alternatives (`libhdf5-serial-dev | libhdf5-dev`) because a
single control file has to satisfy every distribution in the matrix. Note that `apt`
installs the *first* alternative it can, so an alternative is not a way to say
"either of these will do" — it only helps where the first one is unavailable.
single control file has to satisfy every distribution in the matrix. An alternative
only helps where the first one is unavailable: `apt` skips the whole group when any
member is already installed or being installed, and its newer solver need not pick
the first one at all. A dependency that some distributions cannot satisfy is gated
on a build profile instead: `qt6-httpserver-dev <!pkg.openmodelica.nomcp>` (jammy has
no QtHttpServer, so apt-build passes `-Ppkg.openmodelica.nomcp` there, and
`debian/rules` fails when the profile is off and CMake did not find QtHttpServer).
* [`rules`](./debian/rules) — a hand-written rules file, *not* the `dh` sequencer. It
configures and builds the tree itself — with CMake, into `obj-<triplet>/` — and then
calls each `dh_*` helper explicitly from the `install` and `binary-arch` targets.

Drop `-Ppkg.openmodelica.nomcp` for any distribution newer than jammy.

The first run takes hours. Afterwards `build-stamp` is cached, so re-running only
`fakeroot debian/rules binary-arch` after another `debian/` tweak takes minutes.
