CPW is described as "public domain" in its README.md, so that should be ok. (I know the concept is poorly-defined in some jurisdictions, hence CC0 and similar, but that seems academic here). The icon situation could be resolved by including separate licenses for the icons only (since the code is clearly not a derived work of them), or by asking the Breeze folks to draw some replacements. The Qt examples code is more of an issue; 3-clause BSD can be relicensed to GPL but I believe not to 2-clause BSD? -Francis
