  Ok Sorted.
  
  For anybody else . its important where you put the includes. Heres mine for example
  

  Code: Select all

  cmake_minimum_required(VERSION 3.4.1)
  
  project(rknn_yolov5_demo)
  
  set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -Wl,--allow-shlib-undefined")
  set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11 -Wl,--allow-shlib-undefined")
  
  # install target and libraries
  set(CMAKE_INSTALL_PREFIX ${CMAKE_SOURCE_DIR}/install/rknn_yolov5_demo_${CMAKE_SYSTEM_NAME})
  
  set(CMAKE_SKIP_INSTALL_RPATH FALSE)
  set(CMAKE_BUILD_WITH_INSTALL_RPATH TRUE)
  set(CMAKE_INSTALL_RPATH "${CMAKE_INSTALL_PREFIX}/lib")
  
  # rknn api
  set(RKNN_API_PATH ${CMAKE_SOURCE_DIR}/../../../runtime/RV1106/${CMAKE_SYSTEM_NAME}/librknn_api)
  set(RKNN_RT_LIB ${RKNN_API_PATH}/armhf/librknnmrt.so)
  
  #Set header file search path
  include_directories(/home/Projects/luckfox/luckfox-pico/sysdrv/source/buildroot/buildroot-2023.02.6/output/host/arm-buildroot-linux-uclibcgnueabihf/sysroot/usr/include)
  
  #Set library file search path
  link_directories(/home/Projects/luckfox/luckfox-pico/sysdrv/source/buildroot/buildroot-2023.02.6/output/host/arm-buildroot-linux-uclibcgnueabihf/sysroot/usr/lib)
  
  
  include_directories(${RKNN_API_PATH}/include)
  include_directories(${CMAKE_SOURCE_DIR}/../../3rdparty)
  
  # rknn_yolov5_demo
  include_directories(${CMAKE_SOURCE_DIR}/include)
  
  add_executable(rknn_yolov5_demo
              src/main.cc
              src/postprocess.cc
  )
  
  
  
  target_link_libraries(rknn_yolov5_demo curl
  ${RKNN_RT_LIB}
  )
  
  # install target and libraries
  set(CMAKE_INSTALL_PREFIX ${CMAKE_SOURCE_DIR}/install/rknn_yolov5_demo_${CMAKE_SYSTEM_NAME})
  install(TARGETS rknn_yolov5_demo DESTINATION ./)
  
  
  install(PROGRAMS ${RKNN_RT_LIB} DESTINATION lib)
  install(DIRECTORY model DESTINATION ./)
  

  
  Thanks for the help guys
