Probably, I can think of hacks to do it, but why do you need to?
local files = [ glob-tree ... ] ;
...
<include>$(files:D)
Someone correct me if there is a better way

I just search all files in the boost-build folder. /usr/share/boost-build
The online docs are rarely useful to me except when I started.

I find it interesting you include everything in the form #include<...>
for a single executable.

Doubtful, there are features that do "similar" things

Generally using #include<...> is reserved for libraries. So in your
code if you have a subdir that could constitute a unit of compilation
you would add a Jamfile there and specify the library to be the
contents of that folder. You could then specify a usage-requirement of
"<include>." which will add that folder to the include search path for
anyone who includes that library in another target.
To include it in Jamroot you would use path/to/subdir//target
I would also recommend using use-project in that case.
