You copy the header in do_install to ${D}${includedir} or a subdir of
that depending on the header.

Cheat sheet:

STAGING_BINDIR -> ${D}${bindir}
STAGING_INCDIR -> ${D}${includedir}
STAGING_LIBDIR -> ${D}${libdir}
STAGING_DATADIR -> ${D}${datadir}

And if your recipe uses BBCLASS_EXTEND = native *and* 'make install'
doesn't do the job (e.g. using do_install_append), use
NATIVE_INSTALL_WORKS = "1"

If you use packaged-staging it's easy to do dpkg-deb -c on the staging
packages before and after the changes.

Koen
