I'll answer the same way I answered in the CMake mailing list that you
posted the SAME question to.
Use find_package(..) then use the variables that FindBoost.cmake
provides you. Consult the original reply from me in the CMake Mailing
list for the rest of the answer.
If you choose to ignore the suggestions made in that posting then you
are really fighting an uphill battle with boost and CMake. If you
choose to accept the suggestion then your life is going to be much
easier. Your Choice.
