This does not seem like the right place to me to adjust the settings. I
think (not sure; never tried it) that the right technique is in the
nativesdk-meson recipe:

    install -d ${D}${SDKPATHNATIVE}/post-relocate-setup.d
    install -m 0755 ${WORKDIR}/meson-setup.py
${D}${SDKPATHNATIVE}/post-relocate-setup.d/

    # We need to wrap the real meson with a thin env setup wrapper.
    mv ${D}${bindir}/meson ${D}${bindir}/meson.real
    install -m 0755 ${WORKDIR}/meson-wrapper ${D}${bindir}/meson

Hi Alex

Thank you for your advice and I have a question.

1:-> This does not seem like the right place to me to adjust the settings.

Well, did you mean that I shouldn’t adjust the settings in meta-environment recipe, instead of it, adjust the settings in the nativesdk-meson recipe?

What I mean is that you take nativesdk-meson recipe as an example of how to
do special configuration for nativesdk, and do similar adjustments to
dnf/rpm recipes. Specifically, the wrapper can set up environment
variables, and the script in post-relocate-setup.d/ can  write
configuration files.
