[vdr] why does the Makefile not install all include files

[Martin Gansser]

why does the Makefile of e.q. vdr-1.7.32 only install the includes from
include/vdr include/libsi and not the dvb* and libhd* files ?

vdr Makefile:
# Includes:

install-includes: include-dir
        @mkdir -p $(DESTDIR)$(INCDIR)
        @cp -pLR include/vdr include/libsi $(DESTDIR)$(INCDIR)
...


I miss the following include files to compile a vdr plugin

/usr/include/vdr/dvbsddevice/dvbsdffdevice.h
/usr/include/vdr/dvbhddevice/dvbhdffdevice.h
/usr/include/vdr/dvbhddevice/hdffcmd.h
/usr/include/vdr/dvbhddevice/libhdffcmd/hdffcmd.h
/usr/include/vdr/dvbhddevice/libhdffcmd//hdffcmd_av.h
/usr/include/vdr/dvbhddevice/libhdffcmd/hdffcmd_generic.h
/usr/include/vdr/dvbhddevice/libhdffcmd/hdffcmd_hdmi.h
/usr/include/vdr/dvbhddevice/libhdffcmd/hdffcmd_mux.h
/usr/include/vdr/dvbhddevice/libhdffcmd/hdffcmd_osd.h
/usr/include/vdr/dvbhddevice/libhdffcmd/hdffcmd_remote.h
