icecc Icecc is outdated: * Latest release is 1.4.0 (2022) which doesn't include lots of nice fixes and features. * Thread Overall status of the project #586 points to use sccache instead of icecream * icecc.bbclass is not maintained and lack support of new Yocto features, generating a lot of problems (i.e. clang)
