Compiling rustcord-sys v0.2.4
error: failed to run custom build command for `rustcord-sys v0.2.4`

Caused by:

My guess is that rustcord-sys 0.2.4 dep uses an outdated version of Rust libclang wrapper, where neither clang.dll nor libclang.dll can be find. I refer to the following issue that has apparently been fixed on 28th July 2019.

You need to add Clang "lib" or "bin" folder to the env.

or typing setx LIBCLANG_PATH "C:\clang\lib"
