Fails to build on debian

[minghia]

After running:
mkdir build
cd build
cmake ..
make
I get the following error:
In file included from /home/avasile/src/yse-soundengine/YseEngine/synth/../midi/../internalHeaders.h:48:0,

#include "portaudio.h"

At which point the compilation fails. There is a portaudio.h. There is a portaudio.h under yse-soundengine/dependencies/portaudio/include/portaudio.h
