Compila perfeitamente, o executável roda perfeitamente até a hora de chamar a função Pa_Initialize(), que dá o seguinte:

Podemos tentar:

  • dar uma simplificada no FindPortAudio.cmake (quem sabe reduzir tudo a um -lportaudio no CFLAGS).
  • googlar esses erros aí
  • dar uma olhada nas configurações de audio do kde
