These options can be used to override the values returned by pcre-config, e.g.
to build using a static PCRE library even if pcre-config prefers to use the
shared one by default.

(in fact, pcre-config isn't even called at all if these options are set).

flags returned by pcre-config, you may set PCRE_LIBS and PCRE_CFLAGS variables
to be used instead. And if you don't have PCRE at all, the configure script
will provide instructions for obtaining it.
To build and install SWIG, simply type the following:
