install pcl-conversions when pcl is already installed

edit

Nowadays I installed PCL from source code because of a bug in pre-built binaries.

And now I want to install two packages ros-indigo-pcl-ros and ros-indigo-pcl-conversions using apt-get command.

But it says pcl-1.7 will be installed again.

I think installing pcl-1.7 again is redundant because I've already installed it from source code.

Is there any way to let apt-get know pcl-1.7 is already installed and skip installing it?

The resulting message of sudo apt-get install ros-indigo-pcl-conversions is as follow.

The following extra packages will be installed: libpcl-1.7-all libpcl-1.7-all-dev libpcl-1.7-bin libpcl-1.7-doc libpcl-apps-1.7 libpcl-apps-1.7-dev libpcl-common-1.7 libpcl-common-1.7-dev
