add_library(stbiw STATIC stb_image_write.cpp),把文件添加到库里
target_include_directories(stbiw PUBLIC .),让要使用这个库的文件,可以像访问当前目录一样访问他
#define STB_IMAGE_WRITE_IMPLEMENTATION, (纯0基础萌新,看视频也找不到答案,不知道需要补什么知识。。)这一步我不懂,根据老师的提示信息,一次次尝试出来的。。。
#include <stb_image_write.h>,添加头文件进去。
我的理解是,stbiw的作用就是将需要的功能打包起来,以后需要用到,直接在CMake里设置导入就行,把功能变成一个个模块,拿过来就用,类似原子性的思想
