can you try using CMake to build? see https://github.com/VSRonin/QtXlsxWriter/issues/12

Example need: https://forum.qt.io/topic/92571/problema-con-segnale-che-viene-emesso-pi%C3%B9-volte

Allow deciding the sort order for each column: https://forum.qt.io/topic/91635/sort-model-select-multi-header-column/

the build works in CI, have a look there if it matches what you are doing: https://ci.appveyor.com/project/VSRonin/qtxlsxwriter/builds/24278289/job/wl3jiogiu0n5vbr8

usually when you change your .pro file you have to re-run qmake, did you do that step?

I'm not completely sure about this. The whole thing is deployed to work as a Qt Module, make install does that. `QT += xlsx` Does the include and linking work...
