CMAKE_PREFIX_PATH not honoured for dependencies

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Invoke cmake with a 
CMAKE_PREFIX_PATH=/some/boost:/some/python:/some/hdf5:/some/ilmbase:/some/pyilmb
ase

What is the expected output? What do you see instead?
It should just work, but I have to set ILMBASE_ROOT, PYILMBASE_ROOT etc.

What version of the product are you using? On what operating system?
1.5.2 on Linux

Please provide any additional information below.
CMAKE_PREFIX_PATH is supposed to make this stuff a lot easier, but I think some 
copy-pasted Find*libs.cmake is getting in the way.
