[pdal] Configuring PDAL basic core library on Unix

[Rory Sutton]

Attempting to configure the basic core PDAL libraries on Unix according to the instructions on the PDAL website, I've encountered a problem.  XML2 seems to be a dependency of pcinfo and the build fails if it is not switched on.

CMake Error at apps/CMakeLists.txt:85 (install):
  install TARGETS given target "pcinfo" which does not exist in this
  directory.

Turning on XML2 gets the build configuration done without error, but the next step, running "make" on it, bombs on Colorization.cpp:

I'm new to PDAL and cmake, so this is probably due to some oversight or misunderstanding on my part.  I'm on Ubuntu 13.04 now, but this behavior was identical on Ubuntu 12.10.  Any clue will probably be rewarded by further questions.
