Failed to compile on machine without Vapor

[fassko]

I was building Websocket and HTTP on Circle CI without Vapor installed.

After having this issue I found from vapor/vapor#1562 that I need to install libressl with brew install libressl

If someone would help me I would like to try to fix myself this.

Error from Circle CI with Xcode 9.3:

On Linux, you need to have the libssl-dev and pkg-config packages installed to get the same development libraries.

It's more effective however to copy/adapt the CircleCI 2.0 configuration from one of the Vapor repos than figuring it out from scratch, however.

[fassko]

Sorry I forgot to mention that it was on macOS and using Circle CI 2.0.

[vzsg]

On macOS, you need to have pkg-config and libressl installed via Homebrew. If those are available, this package should compile just fine.

Thanks @vzsg for the tips. I think we can close the issue.
