I was searching for quite some time and still haven't found a solution to this question: How can you create your own Camera applications using the qmmf API? I can see minimal examples in the docs generated with doxygen from the yocto repository checked out, and I have used the instruction `bitbake <image> -c populate_sdk` to create an SDK and it worked. But when I try to compile camera applications by hand outside of the yocto repository, e.g. the code files in qmmf-sdk/recorder/test/gtest/, many headers are still missing. Is there any Qualcomm pdf describing the process?
