Subject: [PATCH] Make cmake to build under Debian

Add a new option, WITH_EMBEDDED_SRC, which default is ON and same as
current setting.
When set to OFF, it can use system's libcork, libcorkipset, and libbloom.

It can be built in debian by:
$ cmake -DUSE_SYSTEM_SHARED_LIB=1 -DWITH_STATIC=OFF -DWITH_EMBEDDED_SRC=OFF
$ make
