Error when building 1.2.1 in Debian (Ubuntu): Missing Qt5 Private Headers

[AxillV]

My guess would be that there is something funky going on with the provided versions of mpv and it's libraries?

Here is the cmake output: [ 44%] Linking CXX static library libhittestwidget.a [ 45%] Building CXX object src/gui/widgets/mpv/CMakeFiles/mpvwidget.dir/mpvwidget.cpp.o [ 46%] Building CXX object src/gui/widgets/mpv/CMakeFiles/mpvwidget.dir/mpvtimer.cpp.o [ 46%] Building CXX object src/gui/widgets/mpv/CMakeFiles/mpvwidget.dir/mpvwidget_autogen/mocs_compilation.cpp.o [ 47%] Building CXX object src/gui/widgets/mpv/CMakeFiles/mpvwidget.dir/osctimer.cpp.o gmake[3]: Leaving directory '/home/user/MementoSource/build' [ 47%] Built target hittestwidget [ 48%] Linking CXX static library libstrokelabel.a gmake[3]: Leaving directory '/home/user/MementoSource/build' [ 48%] Built target strokelabel /home/user/MementoSource/src/gui/widgets/mpv/mpvwidget.cpp:35:10: fatal error: qpa/qplatformnativeinterface.h: No such file or directory 35 | #include <qpa/qplatformnativeinterface.h> | ^~~~~~~~ compilation terminated. gmake[3]: [src/gui/widgets/mpv/CMakeFiles/mpvwidget.dir/build.make:104: src/gui/widgets/mpv/CMakeFiles/mpvwidget.dir/mpvwidget.cpp.o] Error 1 gmake[3]: Waiting for unfinished jobs....

You're missing the private Qt headers. RHEL and Debian like to separate them out into their own packages for some reason. Install the qtbase5-private-dev package.
