Is the lower-case "b" in "find_package(boost ...)" just a typo? On
Linux, this CMakeLists.txt file fails completely as Boost must be
requested with upper-case "B", i.e. "find_package(Boost ...)".

Additionally, I get the following:

[...]
-- Boost version: 1.43.0
-- Found the following Boost libraries:
--   unit_test_framework
-- Boost_VERSION=104300
[..]

The line containing "Found the following..." and the subsequent list of
detected Boost libraries are missing in your log. Furthermore, I can
reproduce your results by issuing "find_package(Boost)", i.e. by not
requesting any of Boost's libraries. Perhaps, this somewhat helps.
