This is not really a bug in Meson, it is how things should work by design. All arguments used for cross compilation come from the cross file only. Envvars are not used for cross compilation, only native compilation. I have attached an updated version of the debcrossgen script that reads the envvars and puts them in the cross file in the proper form. Can you test if it fixes the issue for you? Note that the script must be run in the build environment so that CPPFLAGS and all the rest of the envvars are set to the values used in the final compilation.
