It would be normal to include these files in the libfluidsynth_devel
package, for use by cmake's find_package command.
Is there some reason to exclude them? If so, a comment explaining why
would be a good idea.

I confirmed that fluidsynth works properly with latest portaudio package.
So, I enabled the support for portaudio. I forgot to delete this line.
Thanks.
I have revised the project files. Could you please recheck them?
