不能使用 Qt Xlsx

cannot use Qt Xlsx

我在 /opt 中安装了 Qt 5.15 Beta-2。我还从 here and built the Qt5::Xlsx module [qmake, sudo make, sudo make install]. Now in /opt/Qt/5.15.0/gcc_64/include there's a directory QtXlsx but it contains only one file QtXlsxDepends. No xlsxdocument.h, xlsxcell.h or anything like that, so Qt Creator says file not found if I try to include them as in here.

the output of the build commands

sought-for headers 在 /opt/Qt/5.15.0/gcc_64/mkspecs/features/include/QtXlsx 中。所以我将 target_include_directories(target PRIVATE /opt/Qt/5.15.0/gcc_64/mkspecs/features/include/QtXlsx) 添加到我的 CMakeLists.txt 并且问题消失了。
