Hi Matt,

If you're using CMake >= 3.0, then there's a Boost_NAMESPACE variable you
can set that will cause the find module look for mangled library names line
myboostnamespace_datetime instead of boost_datetime. You can generate a
source tree with an alternate namespace using the boost bcp tool. I know
that doesn't seem to be your issue at the moment but it could help in
making sure your system boost doesn't get found.

Unrelated to your issue, but in general, when testing boolean variables in
CMake, it's best to treat them as a true/false value instead of integers or
strings. So instead of "if(Boost_FOUND EQUAL 0)", use "if(NOT
Boost_FOUND)". The reasoning is that there are many different ways to
create true/false boolean values in cmake. For example, a false boolean
value can be represented as NO, 0, FALSE, OFF, "", etc. By just letting the
variable act as a boolean, it streamlines the code needing to deal with it.

Without that, it's just going to look in the same places as before.
Also try setting Boost_DEBUG=ON before the find package calls. This will
output some additional debugging information for the find module regarding
what and where it's actually searching for.
