When we take a library package we depend on (e.g., LIBPCRE) from a directory other than the default location of the system, we add the same directory twice on the linker command like, like so: EXTLIBS += -L$(LIBPCREDIR)/$(lib) $(CC_LD_DYNPATH)$(LIBPCREDIR)/$(lib) Introduce a template "libpath_template" that takes the path to the directory, which can be used like so: EXTLIBS += $(call libpath_template,$(LIBPCREDIR)/$(lib)) and expand it into the "-L$(DIR) $(CC_LD_DYNPATH)$(DIR)" form. Hopefully we can reduce the chance of typoes this way.
