nmake is in between implicit and explicit
library assertions allow library prerequisites
foo :LIBRARY: foo.c -lbar -lbam
the -l* prereqs of :LIBRARY: that exist are added as implicit prereqs of
the target library
e.g., suppose -lbar exists but -lbam does not
then every makefile prereq
-lfoo
will expand to
-lfoo -lbar
(and the build of foo will not complain about -lbam not existing)
so
cmd :: cmd.c -lfoo
will link these libraries
-lfoo -lbar
but the makefile must explicitly assert the -lfoo prerequisite
the implicit prerequisites for -lfoo are in the generated file
$INSTALLROOT/lib/lib/foo
hope that helps
