MAKE process error on Debian 10

[Suitear]

I have QT5 installed.

But this error pop out when executing 'make' command

/home/user/torrent-file-editor/bencodemodel.cpp: In member function ‘void BencodeModel::appendRow(const QModelIndex&)’: /home/user/torrent-file-editor/bencodemodel.cpp:562:32: error: unknown option after ‘#pragma GCC diagnostic’ kind [-Werror=pragmas] #pragma GCC diagnostic ignored "-Wdeprecated-copy" ^~~~~~~~~~~~~~~~~~~ cc1plus: all warnings being treated as errors make[2]: *** [CMakeFiles/torrent-file-editor.dir/build.make:415: CMakeFiles/torrent-file-editor.dir/bencodemodel.cpp.o] Error 1 make[1]: *** [CMakeFiles/Makefile2:73: CMakeFiles/torrent-file-editor.dir/all] Error 2 make: *** [Makefile:130: all] Error 2

Similar -Werror=deprecated-delcaration building on Debian 11 with qt5 (because apparently qt4 is no longer in Debian repos):
