Installing mockgen does not get added to path

[pickfire]

Actual behavior Mockgen was added in ~/src/go/bin/mockgen by installing it with GO111MODULE=on go get github.com/golang/mock/mockgen@v1.4.4, but no warnings were given that ~/src/go/bin is not part of PATH environment variables.

Expected behavior A clear and concise warning should be given to users when installing.

To Reproduce Steps to reproduce the behavior

1. GO111MODULE=on go get github.com/golang/mock/mockgen@v1.4.4

Additional Information

• gomock mode (reflect or source):
• gomock version or git ref: v1.4.4
• golang version: go version go1.15.2 linux/amd64

Triage Notes for the Maintainers

Hey,

All go binaries are by default installed to $GOPATH/bin. It is common practice to add this location to your PATH. It is the responsibility of the user to do so.

There is no warning we could provide in the tooling, but we could add a note to our README. Feel free to open a PR if you are willing.
