[CMake] install TARGETS given unknown argument "EXPORT". with cmake 2.8.9

[david.hagood at gmail.com]

I am trying to set up component registration as per

http://www.cmake.org/Wiki/CMake/Tutorials/Packaging

but when I run Cmake I get the error

  install TARGETS given unknown argument "EXPORT".


While I've found many hits on Google with that error string, none that I
have found have any resolution on what to do about it. Is the tutorial
page in error?
