Not sure why it can't libpf_igl.so but I think I can explain the make
behaviour (although I do not have direct access to the 2.1 versions).

In the first case when you make everything, my guess is that the first target
in the make file looks something like this:

default: ogldso

Which tells it to make all the OpenGL versions with dynamic linking (the
default in my 2.0 Makefile is igldso).

Now when you try to just make one of them (here's the second guess...based on
my 2.0 Makefile) it bypasses the default target and the first one that
it appears to match is:

$(TARGETS): $(++at++:=.igldso)

and when I change the igldso to ogldso and type "make simple," it creates an
OpenGL version.
