python3 path different from python2

Hi all - 

I'm working with rocko trying to build a recipe with python3 that used to be build with python2 using cmake. After changing things in the build files, when I run the devshell for the recipe, I see two different include paths for python2 and python3. I have tried switching to zeus but I had a few issues with a xilinx bsp for the machine I wanted to build with. 

For python2 (correct):
root@dc:/local/d6/easmith5/rocko_bitbake/poky/build/tmp/work/aarch64-poky-linux/opc-ua-server-gfex/1.0+gitAUTOINC+921c563309-r0/git# python-config --cflags
-I/local/d6/easmith5/rocko_bitbake/poky/build/tmp/work/aarch64-poky-linux/opc-ua-server-gfex/1.0+gitAUTOINC+921c563309-r0/recipe-sysroot/usr/include/python2.7 -I/local/d6/easmith5/rocko_bitbake/poky/build/tmp/work/aarch64-poky-linux/opc-ua-server-gfex/1.0+gitAUTOINC+921c563309-r0/recipe-sysroot/usr/include/python2.7 -fno-strict-aliasing -O2 -pipe -g -feliminate-unused-debug-types -fdebug-prefix-map=/local/d6/easmith5/rocko_bitbake/poky/build/tmp/work/aarch64-poky-linux/python/2.7.14-r1=/usr/src/debug/python/2.7.14-r1 -fdebug-prefix-map=/local/d6/easmith5/rocko_bitbake/poky/build/tmp/work/aarch64-poky-linux/opc-ua-server-gfex/1.0+gitAUTOINC+921c563309-r0/recipe-sysroot-native= -fdebug-prefix-map=/local/d6/easmith5/rocko_bitbake/poky/build/tmp/work/aarch64-poky-linux/opc-ua-server-gfex/1.0+gitAUTOINC+921c563309-r0/recipe-sysroot= -DNDEBUG -g -O3 -Wall -Wstrict-prototypes

For python3 (incorrect):
root@dc:/local/d6/easmith5/rocko_bitbake/poky/build/tmp/work/aarch64-poky-linux/opc-ua-server-gfex/1.0+gitAUTOINC+921c563309-r0/git# python3-config --cflags
-I/usr/include/python3.5m -I/usr/include/python3.5m  -Wno-unused-result -Wsign-compare -g -fstack-protector-strong -Wformat -Werror=format-security  -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes

The python3 one is obviously incorrect, is there a way to tell where this path is coming from? Even if I manually include the proper path in the CMakeLists.txt it doesn't seem to work. Does yocto overwrite this path somewhere? 

Thanks!
