I would like to revive this question.

When I do this:

FIND_PACKAGE(Boost 1.51 COMPONENTS program_options required)

I see a variable Boost_DIR that gets set to Boost_DIR-NOTFOUND, even
though Boost_INCLUDE_DIR, Boost_LIBRARY_DIRS, and a whole bunch of
other variables are set correctly, and the project builds correctly.
Is there something else you have to do to get Boost_DIR to not say
NOTFOUND?

Thanks,

David
