How to resolve this problem?

Are you trying to build version 1.4.0 of the Workbench source (1.4.0 is in the title of your message)?

Do you need to build workbench from source? There appear to be some Debian and Ubuntu versions for 'amd64' at http://neuro.debian.net/pkgs/connectome-workbench.html.

I don't know if this will help because I would expect PKG_CHECK_MODULES to search /usr/include, but you can add paths for CMake to search by defining both CMAKE_PREFIX_PATH and PKG_CONFIG_USE_CMAKE_PREFIX_PATH. I believe you can define these when running cmake -D PKG_CONFIG_USE_CMAKE_PREFIX_PATH=TRUE -DCMAKE_PREFIX_PATH=/usr
