install headers for an application

[Sebastian Reitenbach]

Hi,

with gnustep make it seems, when I have an application project, it does ignore 
the AppName_HEADER_FILES AppName_HEADER_DIR and AppName_HEADER_INSTALL_DIR 
variables.
Why do I need it, I want to add CDPlayer and Burn to the OpenBSD ports tree. 
Burn needs a header file from CDPlayer which defines a Protocol. The FreeBSD 
port just installs this header file via the Ports Makefile, what I also do 
right now. But because this pollutes the ports makefile, I'm wondering, if 
there already is a functionality which I could use, within gnustep-make or 
whether it could be added to gnustep-make so that App projects can install 
header files?

cheers,
Sebastian
