--target is not always a valid command

For example Google's BoringSSL can't be build with this crate as it --target isn't a valid cmake command for it.

I don't know how to disable it but the default of --target "install" causes a build error.

Interesting! Maybe we could add an option like no_build_target which disables passing the --target flag to cmake?

[valarauca]

That should work.

I guess the only other approach would be an Option<String>, but that would be a breaking api change.

👍

Yeah we can probably do that eventually but for now stick with the backwards compatible option. Would you be willing to send a PR to test this out?

[valarauca]

Currently traveling I'll try to submit soon.

Ok, thanks!
