Make install not pointing to customised sdk

Hi,
In my docker file there is a command make install which is supposed to target my customised sdk but actually it is searching functions of my customised sdk online and erroring out as:
x/kvstore/client/rest/rest.go:129:13: undefined: “github.com/cosmos/cosmos-sdk/x/auth/types”.NewTxBuilderFromJSON
x/kvstore/client/rest/rest.go:147:16: undefined: utils.SignStdTxPass
I want to know what changes i have to make so that make install target correct file ie. my customised one.
