To do that you have to get a list of the (recursive) dependencies of
the IDE. I quickly made a Gambas script that can do that (but it is
not completely bug-free because it's hard to determine which files
in the source tree describe a component and which are *templates* for
component description files!). If the immediate dependencies are
enough, it is a simple matter of:

  $ sed -n 's/Component=\(.*\)/\1/p' <app/src/gambas3/.project
  gb.image
  gb.gui.qt
  gb.form
  gb.clipper
  gb.db
  gb.db.form
  gb.debug
  gb.desktop.x11
  gb.desktop
  gb.eval
  gb.eval.highlight
  gb.form.dialog
  gb.form.editor
  gb.settings
  gb.form.mdi
  gb.form.stock
  gb.term
  gb.form.terminal
  gb.gui.qt.webkit
  gb.net
  gb.net.curl
  gb.markdown
  gb.signal
  gb.util

This could be built into the configure script, I suppose, and matched
against the list of disabled components.

There is also an explicit listing of the dependencies of the IDE at [1].
It currently matches the output of my script, so whoever maintains it
seems to be more dependable than I would have imagined :-)

However, I wouldn't call any component but gb necessary. I run a small
Gambas on a CentOS 6.9 server as well. It has neither the IDE nor most
of the necessary components. It has the hand full of components I need
though.

Tobi
