I am trying to use the DSP library for my XCORE-200 MC Audio. I am using the DSP library which I obtained from here: https://github.com/xmos/lib_dsp/tree/master
My method of importing the library to my workspace is as follows: download the Zip from GitHub, extract the zip to the workspace location, and use xTimeComposer to import an existing project into the workspace.
The Zip I downloaded comes with many examples that use lib_dsp. I am able to successfully run several of these examples (i.e. app_adaptive). However, when I #include <dsp.h> in my project and build it, I receive errors:
So the error seems to show that there is an issue with the file dsp_adaptive.c because it cannot find one of the lib_dsp header files - dsp_qformat.h. But why would dsp_adaptive.c not work for my project, but work for the examples? There must be an issue including the header file locations in my project, but I can not find what it is.

What I have tried:
As a temporary fix to this problem, I can modify dsp_adaptive.c and change the line from "#include dsp_qformat.h" to "#include "../api/dsp_qformat.h". Then the error will go away, but the next header file (dsp_math.h) in dsp_adaptive will give a similar issue. So I can prefix the ../app/ path to every header include statement, but then a different file than dsp_adaptive gives me problems. So I do not think this is an appropriate fix.
I have also examined my projects properties -> C/C++ General -> Paths and Symbols -> Include directories and verified that /lib_dsp and /lib_dsp/src and /lib_dsp/api are all present.
How can I successfully build my project with this library and use the header files? Thank you.
