To build voxl-qvio-server, please follow the instructions in the README. The instructions are validated nightly by the CI
The first paragraph of the README explains the following: "Due to MV SDK being 32-bit only, this is the only 32-bit package for QRB5165. The APQ8096 package builds in voxl-emulator, the QRB5165 package builds in qrb5165-emulator using a 32-bit cross compiler installed in the emulator."
the only way to build that package is to follow the instructions in the README. Installing your own compiler will not work, you need to use the toolchain provided.
