dnl pkg-config does not output xapian include flags when the include
dnl path is already in CPATH. See
dnl https://unix.stackexchange.com/questions/362289/why-is-pkg-config-cflags-openssl-returning-nothing-on-rhel-6-8
dnl But, swig does not use CPATH. So, we need to invoke pkg-config
dnl again forcing it to output all include flags.
