Bitbake build for qpid-cpp-1.39.0 fails - bitbake

Question

I must preface this saying I have very little knowledge of Yocto/Bitbake, make, cmake, autoconf, etc.
I have an application, written in C++, that I have been unable to get built. The issue I am having is that I have been unable to get some dependencies built in Yocto/Bitbake. The application has dependencies on the following libraries:
Paho-MQTT (https://github.com/eclipse/paho.mqtt.c.git)
Jansson JSON parser (http://www.digip.org/jansson/releases/jansson-2.10.tar.gz)
Apache QPID C++ (https://www-us.apache.org/dist/qpid/cpp/1.39.0/qpid-cpp-1.39.0.tar.gz)
When running the bitbake recipe for apache qpid, I am receiving the following error:
CMake Error at src/CMakeLists.txt:84 (message):
| Can't find amqp 0-10 spec for framing code generation
I do not have any ideas how to get past this error.
I am running Docker/Yocto on a Macbook and have followed the instructions to get everything installed and running. The application (and dependent libraries) are being compiled for a Multitech Conduit gateway running mLinux version 4.1.6. I followed the instructions at http://www.multitech.net/developer/software/mlinux/mlinux-building-images/building-a-custom-linux-image/ to download and build the default images for mLinux 4.0 and higher.
I could not find an existing recipe for building qpid-cpp-1.39.0. I was able to find a recipe for qpid_0.20 (http://git.yoctoproject.org/cgit/cgit.cgi/meta-cloud-services/tree/meta-openstack/recipes-extended/qpid/qpid_0.20.bb?h=master) that I attempted to modify to support qpid-cpp-1.39.0. When running bitbake against the recipe, I receive the following output:

Knowing that I have just started learning Yocto/Bitbake just three days ago, I'm hoping that someone out there can help me determine what the problem is so that I can compile the apache qpid-cpp-1.39.0 library for mLinux.

According to find_file documentation:
The CMake variable CMAKE_FIND_ROOT_PATH specifies one or more
directories to be prepended to all other search directories. This
effectively “re-roots” the entire search under given locations. Paths
which are descendants of the CMAKE_STAGING_PREFIX are excluded from
this re-rooting, because that variable is always a path on the host
system. By default the CMAKE_FIND_ROOT_PATH is empty.
And since cmake called from bitbake environment is effectively a cross-compilation, then this variable should be also ignored. I added a patch files/0001-Qpid-cross-compile.patch, which worked for me:
diff --git a/src/CMakeLists.txt b/src/CMakeLists.txt
