Hi,
I have pushed a branch on my repo:
https://github.com/clementperon/meta-openembedded/tree/test_protobuf
and tried to reproduce the issue on my setup with the following kas yaml file.
But I don't see any issue at the configure stage.
cat XXXX/cortexa57-poky-linux-musl/test-protobuf/0.3/temp/log.do_configure
Show that -- Version:23.4.0 of Protobuf is found without any issue
Cmake host version is
$> cmake --version
cmake version 3.27.7
I'm missing something ?
Regards,
Clement
