<implicit-dependency> doesn't have to be precise.
It only indicates a /potential/ dependency for
the include scanner to resolve. Thus, you can do
something like:

exe tool : file1.cpp file2.cpp file3.compil file4.compil ;

All the #includes will be resolved automatically.
If you have separate targets, then you need
something like:

cpp file3.cpp : file3.compil ;
cpp file4.cpp : file4.compil ;

alias headers : file3.cpp file4.cpp ;

for local i in 1 2 3 4 {
  obj file$(i).o : file$(i).cpp : <implicit-dependency>headers ;
