wrap CMake error

[Varun Agrawal]

When setting CMAKE_BUILD_TYPE=Debug, running make fails with this error

libwrap_libDebug.a(Module.cpp.o): In function `boost::filesystem::create_directories(boost::filesystem::path const&)':
/usr/local/include/boost/filesystem/operations.hpp:566: undefined reference to `boost::filesystem::detail::create_directories(boost::filesystem::path const&, boost::system::error_code*)'

This seems to be due the way WRAP_BOOST_LIBRARIES is set in wrap/CMakesLists.txt where optimized is repeated instead of the second one being debug.

@dellaert the fix is really easy. Just update to

set(WRAP_BOOST_LIBRARIES
  optimized
    ${Boost_FILESYSTEM_LIBRARY_RELEASE}
    ${Boost_SYSTEM_LIBRARY_RELEASE}
    ${Boost_THREAD_LIBRARY_RELEASE}
  debug
    ${Boost_FILESYSTEM_LIBRARY_DEBUG}
    ${Boost_SYSTEM_LIBRARY_DEBUG}
    ${Boost_THREAD_LIBRARY_DEBUG}
)

I'm submitting a PR once the make check passes.
