And on most distros you might want to use rtaudio-config to find out the
appropriate linker and compiler flags:

 LIBS=`rtaudio-config --libs`
 CFLAGS=`rtaudio-config --cxxflags`

 etc.

 And then use these in your compiler invocation/makefile. BTW, hint to
 the portaudio developers: there's a rather standard tool for such tasks
 called pkg-config. It might be a good idea to supply a portaudio.pc
 file instead of/together with the rtaudio-config program.
