需求
在C++第三方库的安装配置时，在链接器输入时需要区分debug版本的lib和release版本的lib，但是某些大型库（比如说OpenCV）里面的lib是很多的，一个个复制文件名粘贴太麻烦了，而且两种版本就差了一个d字母，很容易看花眼。所以写了一个小脚本，自动提取lib目录下debug版本和release版本的lib文件名，分别写入到两个txt里，然后配置的时候直接复制整个txt里的文件名到链接器输入就好了。
代码
import os
def Extract_lib(path):
release = open("release_lib.txt", 'w')
debug = open("debug_lib.txt", 'w')
for file in os.listdir(path):
if file[-5:] == 'd.lib':
debug.write(file)
debug.write('\n')
elif file[-4:] == '.lib':
release.write(file)
release.write('\n')
debug.close()
release.close()
if __name__ == '__main__':
path = r"D:\Program Files (x86)\OPenCV\x64\vc16\lib"
Extract_lib(path)
效果
以OpenCV 4.5.5 的为例，输入其lib目录：
