[pdal] PDAL 1.4 compile error

[Andrew Bell]

Alex,

This indeed seems to be a bug in your compiler:
http://stackoverflow.com/questions/35131734/undefined-reference-when-using-lambda

If you're willing to try your compiler with the master branch, I can push a
change that should get around the issue.  I think our use of that construct
is pretty limited, so this might get things working for you.  If things
compile/link I can backport the change to 1.4.
