Basically, that was not a suggestion to change stuff and no criticism
towards the build system. If my writing could be understood in this
way, then I apologize.

I suppose that the principal difficulty for newcomers is, that the
ALL_PKG_FLAGS are not auto-"magically" added at some point (e.g. by
the duneproject script). So one has to know that they are there. I
remember also that I had a similar problem at one point and was first
looking at missing paths in the respective DUNE_[modname]_XXXFLAGS
variables until I realized that these were not the variables to look
at. I do not even remember if this was dune-fem or something else.
Nothing is wrong with with the way things are done now.

Exactly. And if you subtract the misleading paragraph about compound
package-CPPFLAGS, that was more or less what my previous post stated.

Cheers,
