How to build qt charts with profile option in mingw64?

[mjs225]

I want to build qt charts with profile options in mingw64 to analyze some performance issues.

In mingw64, the available profile tool I know is gprof. For gprof to work, the code needs to be compiled with -pg -no-pie, and cannot be linked dynamically.

I've cloned code from https://code.qt.io/qt/qtcharts.git and found the default build option creates a shared library. The chart library is added via cmake function qt_internal_add_module. How can I build qt charts as a static library, with compile option -pg -no-pie? Thanks for any help.
