c++ - Specify delay loading dll with #pragma in the cpp file

Question

I have a static-linked library which uses some functions from a dll which i need to delay-load. So in my executable's properties i've added this dll under Linker/Input/Delay Loaded DLLs. I can't add this option in the lib itself since it doesn't have the Linker property pages (because it's a static lib)
So now whenever i use this lib in another executable tool i need to add the delay-loading option over and over again, which i want to avoid. I know there used to be a pragma for this

#pragma comment(linker, "/DELAYLOAD:mydll.dll")

However it doesn't work for me because it says

warning LNK4229: invalid directive '/DELAYLOAD:mydll.dll' encountered; ignored

Is there a way out, other than LoadLibrary?

对谷歌做了一些研究（像你一样），因为我一直对这些事情感兴趣。明显的链接是：

不幸的是，它是从 2004 年开始的，那是 9 年和之前的一些 VS 版本。

但它变得更糟，我还发现了这个：

这晚了一年，听起来很合理：

不，这从来没有可靠地工作过。在 6.0 中允许它是一个错误。我们稍后通过添加警告修复了一个。
