[Buildroot] CMake can't find Boost

Hi,
I've had a lot trouble convincing cmake that boost is available. I'm
trying to add the UHD drivers to buildroot. We need it to connect up the
USR B200 to our Odroid C1s.
My uhd.mk looks like:
################################################################################
#
# UHD driver for USRP hardware (ettus research)
#
################################################################################
UHD_VERSION = 003_009_001
UHD_SOURCE = /release_$(UHD_VERSION).tar.gz
UHD_SITE = https://github.com/EttusResearch/uhd/archive
UHD_INSTALL_STAGING = YES
UHD_INSTALL_TARGET = YES
UHD_CONF_OPTS += -DENABLE_EXAMPLES=OFF
UHD_CONF_OPTS += -DENABLE_USB=ON
UHD_CONF_OPTS += -DENABLE_MANUAL=OFF
UHD_CONF_OPTS += -DENABLE_DOXYGEN=OFF
UHD_CONF_OPTS += -DENABLE_UTILS=OFF
UHD_CONF_OPTS += -DENABLE_TESTS=OFF
UHD_CONF_OPTS +=
-Dtarget_link_libraries=/data/Build/buildroot/output/target/usr/lib/
UHD_CONF_OPTS += -DBoost_INCLUDE_DIR=../../../../output/build/boost-1.60.0
UHD_CONF_OPTS +=
-DBoost_LIBRARY_DIR=../../../../output/host/usr/arm-buildroot-linux-gnueabihf/sysroot/usr/lib
UHD_CONF_OPTS += -DCMAKE_FIND_ROOT_PATH_MODE_INCLUDE=BOTH
UHD_DEPENDENCIES = libglib2 host-pkgconf python-mako libusb boost
UHD_SUBDIR = host
UHD_SUPPORTS_IN_SOURCE_BUILD = NO
define UHD_PRE_CONFIGURE_FIXUP
cp -r output/target/usr/lib/python2.7/site-packages/mako
output/host/usr/lib/python2.7/site-packages/
endef
UHD_PRE_CONFIGURE_HOOKS += UHD_PRE_CONFIGURE_FIXUP
$(eval $(cmake-package))
And an attempt at building it looks like (full paste at:
http://pastebin.com/eQmf0YW8):

The uhd.mk file is similar to what worked several months ago, but it
appears I didn't event commit to my local repository correctly as trying
to make that doesn't work either.
Should a cmake project using boost 'just work' & I should be complaining
to the UHD guys or is there something I should be tweaking in buildroot?
