Cross compiling Aravis for an ARM aarch64 through a Ubuntu virtual machine

[RubenBelge]

I'm trying to cross compile Aravis from a Ubuntu 22.04 LTS on a virtual machine to an ARM Cortex A-53 with aarch64 architecture. I succeeded in creating the meson cross build but once I try to compile, be it with ninja or meson compile, I get the error that it can't find a certain header file (unicode/ucnv.h). It is located on the Ubuntu machine, since I can find it.

Hello
Since you compiled on Linux, Aravis could be used for windows and Linux, I think there is a question of coding.
I'll add to your question:
Is there any "ANSI" "Unicode" to enable or disable, we are using on Linux machines?
The included files in meson are generated by meson in a JSON file, how we could informe meson to include the <unicode/ucnv.h> ?
Thank you in advance,
