Given the function $f(x)=\sin (2x+ \frac {π}{3})+ \cos (2x+ \frac {π}{6})+m\sin 2x$ $(m∈R)$, and $f( \frac {π}{12})=2$.
(I) Find the value of $m$;
(II) In $\triangle ABC$, the sides opposite to angles $A$, $B$, and $C$ are $a$, $b$, and $c$ respectively. If $b=2$, $f( \frac {B}{2})= \sqrt {3}$, and the area of $\triangle ABC$ is $\sqrt {3}$, find the perimeter of $\triangle ABC$.
