i see. i think i have already asked about that some time ago :)

without the headers, its difficult to compile plugins. the old build
system currently also skips them. i think ${pkgincludedir} =
${includedir}/gnucap is a good place for these headers.

there's one library and a plugin. i think it's most appropriate to
install the library to ${libdir} ("/usr/lib", usually) and the plugin(s)
to ${pkglibdir} (defaults to ${libdir}/gnucap). cmake apparently tries
to support gnu-style [1], i'm not sure to what extent.
