Can't build ldas-tools-framecpp-swig on CIT (ldas-pcdev4)

I am trying to build the framecpp-swig package on the SL7 testing machine ldas-pcdev4.ligo.caltech.edu, using the same instructions as in the spec file, as follows:

#!/bin/bash

set -e
set -x

BUILDDIR=$(mktemp -qd)

trap "{ popd; rm -rf $BUILDDIR; }" EXIT

pushd $BUILDDIR

wget http://software.ligo.org/lscsoft/source/ldas-tools-framecpp-swig-2.6.4.tar.gz

tar -xf ldas-tools-framecpp-swig-2.6.4.tar.gz
cmake3 \
    -DENABLE_SWIG_PYTHON2=yes \
    -DPYTHON2_EXECUTABLE=$(which python2.7) \
    -DENABLE_SWIG_PYTHON3=yes \
    -DPYTHON3_EXECUTABLE=$(which python3.4) \
    -DCMAKE_BUILD_TYPE=RelWithDebInfo \
    -DCMAKE_EXPORT_COMPILE_COMMANDS=1 \
    -DCMAKE_INSTALL_PREFIX=${BUILDDIR}/inst \
    ldas-tools-framecpp-swig-2.6.4

make install

My build fails because it can't find the header files:

What magic option can I provide to get /usr/include included in the search path, I would have presume this to be default. Any help is greatly appreciated.
