curl, tried "libcurl.dll", "curl.dll"

A libcurl.dll comes with the installer. It can be found by your 
program if it's located in the same folder as the executable or 
if the %PATH% environment variable contains the directory where 
the installer puts the DLL in.

You may find this path in the environment variable but it has to 
match 32/64bit. If your 64bit program tries to load the 32bit 
variant it will fail to load.

It's likely that your %PATH% environment variable contains the 
32bit path (eg. for DMD `C:\install-dir\dmd2\windows\bin` but not 
the path to `\bin64`.

So you have to adjust the environment variable or copy the DLL 
from this path to your program executable.

Are you running it from a WSL session? I get libcurl.dll errors 
(although a graphical popup) when I run my thing from in there, 
but it works well from a normal command console and/or Powershell.
