GNU automake CPPFLAGS for individual files
I don't know; maybe I'm just stupid now, but I really haven't been able to find anything on this.
Say I'm configuring a program with automake, and I want to compile some source files in the same subdir with different CPPFLAGS than others. In this case, I want to compile one file with the GTK+ include directories and some other without. I know that you can specify specific LDFLAGS for different targets, and so I think that there should be something similar for CPPFLAGS as well.
Now of course it doesn't _hurt_ to compile the other files with the GTK include directories, but I must say that it doesn't feel clean to compile files with unneccessary CPPFLAGS.
When I look at the generated Makefile, there doesn't appear do be support for that, but I though I'd ask just to be sure.
