[Bug] compile tvm_rpc without hexagon causes missing -lcdsprpc

[pfk-beta]

When I run command to compile tvm_rpc, i'm getting error, that linker cannot find -lcdsprpc, which I think is compiled/added during Hexagon module. My compilation command:

RUN mkdir -p /workspace/build && \
 cd /workspace/build && \
 cp /workspace/cmake/config.cmake . && \
 sed -i 's/set(USE_LIBBACKTRACE AUTO)/set(USE_LIBBACKTRACE OFF)/g' config.cmake && \

During Cmake I see:

My SoC is Mediatek Helio P22 MT6762

As a workaround, you can add -DUSE_HEXAGON_SDK=OFF to your cmake command, or change line 48 in apps/cpp_rpc/CMakeLists.txt from

if (BUILD_FOR_ANDROID AND USE_HEXAGON_SDK)

to

if (BUILD_FOR_ANDROID AND USE_HEXAGON)

Thanks, argument in cmake command doesn't work. If anyone needs, this is sed command: sed -i 's/if (BUILD_FOR_ANDROID AND USE_HEXAGON_SDK)/if (BUILD_FOR_ANDROID AND USE_HEXAGON)/g' ../apps/cpp_rpc/CMakeLists.txt (run from build folder)
