Make install doesn't copy the LASZip header files mydefs.hpp and laszip.hpp which are referenced by lasdefinitions.hpp (resulting in builds that link to laslib failing).
Simple fix is to copy these two files in to the /usr/local/include/laslib/ directory together with the other files. Better fix may be to make install the full laszip library along with laslib.
