Cmake简要配置

编译文件

cmake --build ./build --config Release

自己的的通用模板，可以用在vscode

#CmakeLists.txt
#设置版本号
cmake_minimum_required(VERSION 3.5)

#设置项目名称和语言
project(myEngine VERSION 0.1.0 LANGUAGES C CXX)

#包含测试
include(CTest)
enable_testing()

#需要的包含目录，这里是头文件，cmake会自动去找这些头文件，这里路径都是相对于CmakeLists.txt的位置
include_directories(include)
include_directories(include/bullet)
include_directories(include/freetypefont)
include_directories(include/freetypefont/freetype)
include_directories(include/freetypefont/freetype/config)
# 有了header，还需要lib
# 添加lib的文件夹，必须在add_executable之前
link_directories(src/libs)

# 设置需要编译的文件路径
set(SOURCES
    src/main.cpp
    src/Assets/Camera.cpp
    src/Assets/LightRenderer.cpp
    src/Assets/Mesh.cpp
    src/Assets/ShaderLoader.cpp
    src/Assets/MeshRenderer.cpp
    src/Assets/TextureLoader.cpp
    src/Assets/TextRenderer.cpp
)

# 添加到自己的项目
add_executable(myEngine ${SOURCES})
# c++版本
set_property(TARGET myEngine PROPERTY CXX_STANDARD 17)

# 这里以后改成相对路径
# 相对路径参考示例：${CMAKE_CURRENT_SOURCE_DIR}/src/libs/glfw3.lib
# 一次添加一个lib的方式
add_library(MyLibName STATIC IMPORTED)
set_target_properties(MyLibName
                    PROPERTIES IMPORTED_LOCATION
                    "C:/Program Files (x86)/Windows Kits/10/Lib/10.0.22621.0/um/x64/OpenGL32.Lib")

# 回答说下面的find_library方式更好,但这里一次只有一个。
# find_library(PROTOBUF_LIBRARY protobuf HINTS /usr/lib/x86_64-linux-gnu)
# target_link_libraries(test PUBLIC ${PROTOBUF_LIBRARY})

# 会自动把文件里面带lib的给你找齐
target_link_libraries(myEngine glew32 glfw3 glfw3_mt glfw3dll BulletCollision BulletDynamics LinearMath freetype)
target_link_libraries(myEngine MyLibName)

cmake本身的一些参数设置模板，也是用在vscode

// CmakePresets.json
{
    "version": 3,
    "configurePresets": [
        {
            "name": "default",
            "description": "Default Settings for my engine",
            "hidden": false,
            "generator": "Visual Studio 17 2022",
            "binaryDir": "${workspaceFolder}/build",
            "cacheVariables": {
                "CMAKE_BUILD_TYPE": "Release",
                "CMAKE_EXPORT_COMPILE_COMMANDS": "YES"
            }
        }
    ]
}
