pkg-cmake: allow to build package in a subdirectory

For some cmake based packages, like GNURadio, it's forbidden to do the
compilation directly in the sources directory. This patch add a new
variable to specify, if needed, the name of a sub-directory used to compile.

[Thomas: put the documentation at the right place in the manual, not
in the middle of the <pkg>_CONF_OPTS description.]
