How do libfprint's meson rules for producing the executable and then
running it look like?
Any meson based recipe has a similar entry in ${WORKDIR}/meson.cross:
exe_wrapper =
'/srv/storage/alex/yocto/build-64-alt/tmp/work/core2-64-poky-linux/glib-2.0/1_2.74.6-r0/meson-qemuwrapper'
And the use of the exe_wrapper is documented here:
https://mesonbuild.com/Cross-compilation.html
