Yes, please!
You are the developer.  Do you also answer in mails, or only through
the user-list?

How does the variant_dir work with SConscript files?
I have following organization
in top folder
  A (component subfolder)
     Sconscript
     Can contain other subfolders, in which the process of calling the
Sconscript of subfolders is repeated.
  B (component folder)
     Sconscript
  C (component folder
     Sconscript
  Sconstruct file

I want a "build" folder in the top folder where each component is
reflected in the build folder, so I have
in top folder
  A
     AA
     AB
  B
  C
  build
     A
     B
     C

but if my Sconstruct call

  o = SConscript(f'{subdir}/SConscript', duplicate=False,
variant_dir='build')


In the Sconscript files


I get
Running sconscript in 01_FBL_IF
No Objects found!
scons: done reading SConscript files.
