Yes - you need to use the .SUBDIRS form with a body.

Note that the normal form without a body

.SUBDIRS: foo bar

is equivalent to

.SUBDIRS: foo bar
   include OMakefile

Here the normal scoping rules apply and as there is no "export", the
subdir's OMakefiles are evaluated in their separate scopes. However, you
can always write things like

.SUBDIRS: foo bar
   include OMakefile
   export

if needed.
