no '--version' option for build command

[0xEAB]

System information

• dub version: 1.11.0+13-gb837cee
• OS Platform and distribution: GNU/Linux 4.18, Ubuntu 18.04
• compiler version *

Bug Description

One can fetch specific version by dub fetch <package-name> --version=<package-version>, but one cannot build this version then since there's not dub build --version=<package-version>.

How to reproduce?

dub fetch dcd --version=0.8.0
dub build dcd --version=0.8.0

Unknown command line flags: --version=0.8.0

Expected Behavior

Support --version for the build command, too.

some would call this a feature request, but I think it's rather a bug that you can fetch a specific version and then building or running it potentially might not use the version you just downloaded.

[Geod24]

The way to specify version of a package is to use pkg@X.Y.Z.
I don't know why dub fetch supports --version=X.Y.Z but it also supports dub fetch dcd@0.9.0 so I'd be in favor of deprecating that switch rather than propagating it.

[Geod24]

--version is deprecated, pkg@spec is the way to go.
