I haven't dug into the error -- I figured you'd probably know straight away.<br /><br />This result is quite encouraging. CMake found the core part of Qt5<br />without issues, and this error is only for the subsequent attempt to<br />find additional components. Furthermore, your analysis of this error<br />was correct; I had misread the documentation and used a Qt prefix on<br />the component names when I shouldn't have. Fixed in revision 13052.<br /><br />So thanks for your report, and please try again with that revision.<br /><br />Alan<br />__________________________<br />Alan W.
