CMakeLists.txt编写

1.CMakeLists.txt模板

一个使用opencv 的 CMakeLists.txt

# cmake最低版本要求
cmake_minimum_required(VERSION 3.0)
# 项目名称
project(trilinear_fast)
set(CMAKE_CXX_STANDARD 11)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11 -march=native -fopenmp -msse -msse2 -msse3 -msse4 -mavx -O2 -DNDEBUG")
set(CMAKE_BUILD_TYPE Release)


#set(OpenCV_DIR /usr/local/lib/cmake/opencv4)
#set(OpenCV_INCLUDE_DIRS /usr/local/include/opencv4)

find_package(OpenCV REQUIRED)
include_directories(include ${OpenCV_INCLUDE_DIRS})

message(STATUS "project name = ${PROJECT_NAME}")
message(STATUS "OpenCV_LIBRARIES name = ${OpenCV_LIBRARIES}")

#添加静态库
file(GLOB_RECURSE SRC  ./src/*.cpp )
add_library(lut3d STATIC ${SRC})



add_executable(${PROJECT_NAME} main.cpp)
# include head file of static lib
target_include_directories(${PROJECT_NAME} PRIVATE ./src)
# 该可执行文件调用的静态库
target_link_libraries(${PROJECT_NAME} ${OpenCV_LIBRARIES} lut3d)

对应的目录：

2.设置编程语言版本

set(CMAKE_C_STANDARD 99)
set(CMAKE_CXX_STANDARD 11)

3.设置编译类型Debug，Release

set(CMAKE_BUILD_TYPE Release)

4.设置获取文件列表

MATH_LIB_SRC 指示：找到的math目录下的 c文件

file(GLOB_RECURSE MATH_LIB_SRC  src/c/math/*.c)
add_library(math STATIC ${MATH_LIB_SRC})

5.添加include目录

表示在src/include/目录中寻找头文件
include_directories(src/include)

6.配置编译选项

add_compile_options命令添加的编译选项是针对所有编译器的(包括c和c++编译器)
CMAKE_C_FLAGS或CMAKE_CXX_FLAGS变量则是分别只针对c和c++编译器

add_compile_options(-Wall -Wextra -pedantic -Werror)
set(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -pipe -std=c99")
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11 -O2 -DNDEBUG")

以上基本覆盖了常用的一些CMAKE 指令, 后续用到再补充文章来源地址https://www.toymoban.com/news/detail-489166.html
