Thanks I had tried that but the extra colon caught me out. Now it works 
but I get some warnings like:
warn: Unable to construct ./lexer

Is there any way to get rid of these?

Here is the Jamfile:

cpp lexer : lexer.gl : : <antlr-name>Simple <antlr-base>Base ;

lib antlr_lib
        :
                Base.gl
                lexer
        ;
        
lib test_lib
        : # sources
                test.cpp
        : # reqirements
                <implicit-dependency>antlr_lib
        ;
