Measuring $\gamma$ with $B$ meson decays to charmed final states at LHCb

Progress made by LHCb towards a measurement of $\gamma$ using $B$ decays to charmed final states is presented. The GLW/ADS analysis of $B^{\pm} \to DK^{\pm}$ using 1.0 fb$^{-1}$ of data taken during 2011 is presented, with a combined 5.8 $\sigma$ observation of $CP$ violation. Updates on time-dependent studies and further time-integrated analyses are also included.
