[Scons-users] Using Alias

[William Blevins]

Pierre-Luc,

The Default target is the root SCons directory, so any targets under said
directory are automatically apart of the Default target since they are
considered dependencies (IE. under the directory).

You can do as you already stated. Reset the Default target to only those
you want to build by default. Consider the following source tree:

   - # (SCons root)
      - src
         - bin
            - exec_1
            - exec_2
            - lib
            - lib_1
            - lib_2
            - lib_3
            - test
         - bin
         - lib
      - examples
         - bin
            - example_1
            - example_2


Original case: all exec, lib, and example build since they are child
targets under the root "." or symbolically #
Build src only: set the Default to the 'src' directory to ensure all
targets under 'src' build. If you only want exec_1 (and all its
dependencies), set Default to 'src/bin/exec_1' (you get it's dependencies
automatically.

V/R,
William
