does this project support to compile on WSL ?

@uyplayer You may have already discovered your answer after a year, but I will explain to others who may have encountered the same error.

The problem with your build process is that /lib/modules/5.10.16.3-microsoft-standard-WSL2/build doesn't exist. This path must include either a symlink or the directory of your Linux kernel source code (containing only the header files should be fine as well). If you had an ordinary Linux distribution you could install a package called linux-headers*, but the version matters, and in WSL2 they use a fork of the Linux kernel, not the mainline one.

Unfortunately, WSL2 does not contain its kernel header files in any of its repositories, therefore you can't compile a kernel module with your default kernel. Packages such as linux-headers-$KVER might work for some cases if you create a symlink manually to what it installs (perhaps? haven't tried it, but it should be fine for the purpose of this repository I believe).

And of course, if linux-headers-$KVER does not work for you, you can clone this repo and build your own kernel. This makes module development much easier (you can setup auto-complete stuff as well with the gen_compile_commands.py script). You can read the build instructions from here.
