NCNN模型部署

自定义项目的CMake配置

# 最低CMake版本要求
cmake_minimum_required(VERSION 3.14.5)
# 项目名称
project(NCNN_TEST)

# 查找OpenCV
find_package(OpenCV REQUIRED)

# OpenCV4编译需要使用C++11
set(CMAKE_CXX_STANDARD 11)

# ncnn项目所在路径，需要替换
set(NCNN_DIR /path/to/ncnn)

# 引入OpenCV和NNCN的头文件
include_directories(${OpenCV_INCLUDE_DIRS})
include_directories(${NCNN_DIR}/build/install/include/)

# 设置OpenCV和NNCN的链接库
set(NCNN_LINK_LIBRARIES ${OpenCV_LIBS} ${NCNN_DIR}/build/install/lib/libncnn.a)

# 源文件
set(SOURCE_FILES example.cpp)

# 使用给定的源文件，为工程引入一个可执行文件，创建目标文件
add_executable(NCNN_TEST ${SOURCE_FILES})

# 将目标文件与库文件进行链接
target_link_libraries( NCNN_TEST ${NCNN_LINK_LIBRARIES} )

---

# 设置cmake版本，如果cmake版本过高，可能会出现错误
cmake_minimum_required(VERSION 3.5.1)
project(NCNN_test)

# 设置C++编译版本
set(CMAKE_CXX_STANDARD 11)

# 设置程序编译出的可执行文件
set(MAIN_FILE main.cpp)
set(EXECUTABLE_OUTPUT_PATH ../)

# 分别设置ncnn的链接库和头文件
set(NCNN_LIBS /ncnn/build/install/lib/libncnn.a)
set(NCNN_INCLUDE_DIRS /ncnn/build/install/include)

# 配置OpenMP
find_package(OpenMP REQUIRED)
if(OPENMP_FOUND)
    message("OPENMP FOUND")
    set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} ${OpenMP_C_FLAGS}")
    set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} ${OpenMP_CXX_FLAGS}")
    set(CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} ${OpenMP_EXE_LINKER_FLAGS}")
endif()

# 配置OpenCV
find_package(OpenCV REQUIRED)
include_directories(${OpenCV_INCLUDE_DIRS})

include_directories(${NCNN_INCLUDE_DIRS})

# 建立链接依赖
add_executable(NCNN main.cpp)
target_link_libraries(NCNN ${NCNN_LIBS})
target_link_libraries(NCNN ${OpenCV_LIBS})
