Installation recommendation

[mrbluecoat]

I tried

go get github.com/globalsign/est
go install github.com/globalsign/est/cmd/estserver
go install github.com/globalsign/est/cmd/estclient

but it gave me these errors:

go install github.com/globalsign/est/cmd/estserver
    go/src/github.com/globalsign/est/internal/mockca/ca.go:39:2: cannot find package "github.com/globalsign/pemfile" in any of:
        /usr/lib/go-1.14/src/github.com/globalsign/pemfile (from $GOROOT)
        /root/go/src/github.com/globalsign/pemfile (from $GOPATH)

go install github.com/globalsign/est/cmd/estclient
cannot find module providing package github.com/globalsign/est/cmd/estclient: working directory is not part of a module

Instead, I just used this for installation:

go get -u github.com/globalsign/est/cmd/estserver
~/go/bin/estserver -version
go get -u github.com/globalsign/est/cmd/estclient
~/go/bin/estclient version
