As a consultant, I saw this dumbing down a long time ago and created no 
end of frustration with troubleshooting.  I guess that is what the event 
log is for, but that has its own issues.

Yep, after looking at many of those including eclipse and netbeans, I 
have ended up with VSCode.

I might suggest thinking about using CMake.  it takes a little getting 
used to, and has a bit of learning curve, but it has good integration 
with VSCode.  I use CMake 0.0.17 (at the time of this writing) and CMake 
Tools 1.3.1 (ditto).

I am not sure if I understand all of what you are attempting to do, but 
CMake can work with a primary projects and sub-projects.

If you decide to get into cross platform projects, vcpkg may not be the 
way to go.

Rather than re-inventing the wheel, maybe try CMake, or another 
established build system.  The structure can be as fiddly as you want, 
and is generally used in many projects.

I have several projects with multiple sub-projects, such as what you 
describe.  And isn't really rocket science, as you desire.

Sorry.  Already did.  This comment should have come first.   But I'm not 
sure why you want to re-invent the wheel with something that already 
integrates with VSCode, and is maintained by Microsoft as a primary 
extension?
