Can't compile the crate without Perl (at least on Windows / my machine) since OpenSSL vendored requires it

[babichjacob]

It was changed in #401 to add openssl with the vendored feature as a dependency, but now I can't compile the crate until installing Perl:

error: failed to run custom build command for `openssl-sys v0.9.103`

Caused by:

I then installed a Perl compiler and it builds successfully.

Do you have the option of removing the dependency on OpenSSL and updating reqwest's features to still be able to compile statically that way?

I now see #388 was a previous attempt to do this but you had to close it because of #340 (comment). Dang, sorry it didn't work out.

Although, I'm testing that change locally and the results seem to be the same...

Hi J,

sorry to see this issue happening with the Windows build. I just merged #406 and about to release 2.8.3 with that included, perhaps it'll build without Perl and only require it in case the linking to OpenSSL is chosen to be static? I'll see if I can get the maintainer of that crate make it work without Perl (I'm surprised that language is still used today in anything modern).

[snshn]

It should now possible build without requiring Perl if --no-default-features is passed. Please feel free to reopen this issue if the problem persists.
