[yocto] Bitbake recipe using CMake that requires python-six as part of compiling?

[Giordon Stark]

Hi all,

I'm struggling with what should be a simple-ish recipe (I think). I'm
writing a recipe implementation for
https://github.com/open62541/open62541 (open62541).
So I start with

devtool add open62541 https://github.com/open62541/open62541.git

then I edit this, so it currently looks like this for me:

SUMMARY = "OPC UA implementation"
LICENSE = "MPL-2.0"
LIC_FILES_CHKSUM = "file://LICENSE;md5=815ca599c9df247a0c7f619bab123dad"
SRC_URI = "gitsm://github.com/open62541/open62541.git;protocol=https"
PV = "0.3+git${SRCPV}"
SRCREV = "a6b99dc0579a53207b7dfe1d16423c2c1daa467e"

S = "${WORKDIR}/git"

# NOTE: unable to map the following CMake package dependencies: Check
Sphinx ClangTools LATEX MbedTLS Valgrind
DEPENDS = "openssl"

inherit cmake pythonnative

# Specify any options you want to pass to cmake using EXTRA_OECMAKE:
EXTRA_OECMAKE = ""

however, when I run devtool build open62541, I get  errors about "No module
named six":

| make[2]: Leaving directory
'/local/d4/gstark/poky/build/tmp/work/aarch64-poky-linux/open62541/0.3+git999-r0/open62541-0.3+git999'

How do I get "python-six" added as part of pythonnative?
