The path was /usr/src/Audio Plugins/ZynAddSubFX_3.0-Zyn_Fusion/zyn-fusion-build
After renaming 'Audio Plugins' to 'AudioPlugins' compilation went fine.

Thanks for the bug report. I can confirm that this is an issue that exists. Since there's an easy workaround it's not something that I'm personally interested in fixing (other issues are currently higher priority), but I'd be willing to help others fix this particular issue, since it shouldn't be too high of complexity.
