Problem compiling qt5-related software

[jlindgren]

Hello!!

I am sure this have came up earlier but I have yet to find a resolution for it.

I have come across a problem to upgrade my gentoo system because of this; I dont think this is gentoo-specific, since very similar errors occur on many systems aparrently, however the difference is the paths in quotation-marks after:"The imported target "Qt5::Core" references the file" differ only for which I can see.

I have heard that double-slashes is not the issue, however there is something missing and I don't know what.
For sure I can submit the whole log, however I thought that perhaps someone recognises this very problem
I just don't understand what it's looking fore here:

Seems like line 15 is garbled - it contains the first part of the path twice. Look at line 27 of your file Qt5CoreConfig.cmake to see if there is an indication of what might cause the error.

Is this error occurring in a CMake generate step, or later?

[jlindgren]

Yes, the line 27 only indicates the case of a FATAL ERROR in case the ${file} does not fulfil, and I don't understand what file that is, in case that is the actual problem?

I think you need to post the CMakelists.txt for the top level project, as well as the command line you are running when this error occurs. It looks to me like an environment or CMake variable that tells it where to look for Qt components is set incorrectly.
