[CMake] CMake 2.8.6 RC3 FindBoost Regression Error

[Michael Jackson]

So was (Boost_NO_BOOST_CMAKE 1) introduced in this version of CMake or Past versions? I will tell you up front that I am only using a subset of Boost that I create with "bcp" from boost itself so there could very well be something slightly "off" with what I have that has been able to get through the previous versions of FindBoost but now with updates to FindBoost it is starting to fail. 
  Just to be clear, add (Boost_NO_BOOST_CMAKE 1) allowed my project to use my own boost version.
