On the Website, there is a set of interconnected pages related
to compiling from source, the Debian package and our DEB depot.
Although these pages have always been superficially kept up-to-date,
the overall presentation feels dated and generally not well organized.
During the last weeks, I have almost entirely rewritten all those pages,
added information about the (now reworked) DEB package, explained the
alternate ways to build from a Debian source package (notably the
`mk-build-deps` for handling the build dependencies, which effectively
the only method which always worked during the last years, since our
DEB package was totally outdated)
Furthermore, I have tested most of the build steps with the current
source trees, repositories and package definition, and finally I
have also updated and polished the front-page of our DEB-Depot
(-> see commit on the depot-Branch)
Wheew ... quite some work done!
Many versions enforced with this changeset are chosen such
as to support Ubuntu/Noble (24.04) and otherwise use versions
reasonably close to Debian-Trixie (≙reference-platform)
Since we now require a fairly modern compiler for C++23,
I have added now an explicit version check, which however
is performed only if the defined compiler is named `g++*`
Furthermore, I combed through all of our build tutorials and documentation pages
and updated a lot of information regarding dependencies and build practices...
