NPAPI-SDK is a bundle of NPAPI headers by Mozilla. This project aims to sort out and package that bundle for 'nix systems, providing a clear way to install those headers and depend on them.

Unlike Mozilla, we are concerned about API compatibility. This is why this project is never going to change its API without bumping version. If necessary, we add third version component for that reason.

The usual way of building against this NPAPI-SDK is to add the following into configure.ac:

PKG_CHECK_MODULES([NPAPI], [npapi-sdk])

And into Makefile.am:

foo_la_CPPFLAGS = ... $(NPAPI_CFLAGS)
foo_la_LIBADD = ... $(NPAPI_LIBS)

While the latter may not be necessary, it is better to include it in case Mozilla starts to require linking against specific library.
