Using CGO_ENABLED=0 for Alpine Linux, etc.

[whosgonna]

I'm sorry that I'm not able to better define the reasoning, etc. on this, however the pre-compiled binary won't work on Alpine linux, and just compiling as indicated in the instructions doesn't work:

git clone https://github.com/miconda/sipexer
cd sipexer
go get ./...
go build .

Setting the env var CGO_ENABLED to 0 when building creates a binary that works (for me) in both the default alpine container as well
as my normal Debian distro:

CGO_ENABLED=0 go build .

Given that this works for me on both, I'm not sure if it's better to have the distributed binary and the instructions always reference this, OR to simply add a note in the installation section? Or maybe this is so obvious to someone working in Go that it's unnecessary?

Thanks for reporting it! I was not aware of CGO_ENABLED=0 being required and haven't used myself so far (Debian and MacOS). I will add a note in the docs for those that hit the same situation.
