The following worked for me when building a native recipe that depends
on Boost Program Options:
https://github.com/advancedtelematic/meta-updater/blob/morty/recipes-sota/sota-tools/sota-tools_git.bb
inherit cmake
DEPENDS = "boost ..."
BBCLASSEXTEND = "native"
I'm no OE expect, so I won't claim this it is right answer, but it does
at least build.
