[pdal] Problem reading LAZ file

[Murphy, Todd]

1. Unsure why it did not pickup up include directory. Have you tried setting it manually? On my Fedora install I cloned the laszip repo from Howards GitHub site (https://github.com/LASzip/LASzip). It installed under /usr/include and /usr/lib.

2.I had an issue with the latest laszip which threw the similar errors you identified with LASzipper and LASunzipper. Recommend using earlier commit (e7065cb) of Laszip. My email discussion with Howard on this follows:


> 2. I just created a new development environment (Fedora 22) using the latest laszip from that repo. I saw you had you had the commit to remove LASzipper and LASunzipper. It appears some of the tests still reference these as well as the lasdump apps in PDAL. I haven’t had time to look into, but did a work around for now. Just wanted you to be aware.



LASzip needs to be pinned to a release version for now. Martin wanted to remove LASzipper/LASunzipper and use his "DLL" interface. We're starting on LAZ 1.4, and I want to get things in place for PDAL to support all of it once that's ready. I started doing interface stuff based on his new DLL thingy, but PDAL/libLAS aren't yet caught up to it. PDAL's docker image is pinned to e7065cbc5bdbbe0c6e50c9d93d1cd346e9be6778 which should be perfectly good going forward until PDAL catches up to LASzip.

The error message:
PDAL: Can't read compressed file without LASzip or LAZperf decompression library.
I've, however, activated the option WITH_LASZIP. I've also cloned the LASZIP repository and installed it. Indeed, pdal ccmake has changed the library field:

LASZIP_INCLUDE_DIR               LASZIP_INCLUDE_DIR-NOTFOUND
LASZIP_LIBRARY                   /usr/local/lib/liblaszip.so
Any ideas?
I've also tried using https://launchpad.net/~pdal/+archive/ubuntu/travis , but that one led to compilation errors. (Dumper.cpp: undefined reference to `LASunzipper::LASunzipper()' )
Cheers,
Pol
