Hi

If you are making ramdisk image from the system - dracut should autodetect 
such case and build the image with lvm2 support inside (unless you've 
instructed in dracut.conf to not doing so).

You can check if you dracut ramdisk image contains /usr/sbin/lvm
and also if dirs  in /usr/lib/dracut/hooks do have lvm2 scripts inside as well 
as /etc/lvm/lvm.conf.

Not really sure how are you trying to build this yourself since the Fedora 
anaconda installer should be doing all of this for you automatically - so how 
did you got to the point you don't get this from your installation time ?
