I have several "modules" within the same build environment.  I create
the cons environment in the main Construct and export it.  Then in the
main directory I modify that cons environment with a bunch of module
specific stuff (like LIBPATH, LIBS, CPPPATH, and CFLAGS).  Here's what
I have in the main Conscript for one of the modules.

Import qw( CONS OS PLATFORM CHIP common SERVERDIR );

$EXPORT = "$SERVERDIR/export";
${$CONS}{LIBPATH} .= "$EXPORT/libs";
${$CONS}{LIBS} .= "-lfoo -lbar -lbaz";
@LIBS = ("$EXPORT/lib/libfoo.a","$EXPORT/lib/libbar.a","$EXPORT/lib/libbaz.a" );
push @{${$CONS}{CPPPATH}}, ("#foodir", "#bardir", "#bazdir");

@files = qw( file1.cpp file2.cpp file3.cpp );

Export qw( CONS OS PLATFORM CHIP common EXPORT);
Build ("#foodir");
Build ("#bardir");
Build ("#bazdir");

Depends $CONS "$EXPORT/$TARGET", @LIBS;
Program $CONS "$EXPORT/$TARGET", @files;

Without the Depends line, none of the libraries get built.
