Hello! I use qt 6 and cmake. I install the qcustomplot library, connected the files, added #include "qcustomplot.h” to “mainwindow.h". Everything is fine, building a project without errors. As soon as I add the widget to the form, convert it to QCustomPlot, an error appears in the automatically generated file "ui_mainwindow.h" in the line #include "qcustomplot.h". tell me what could be the problem?
