Building Latest QGC in Android 4.4

Hello, I have been trying to get the current version of QGC to compile and run Android 4.4 (API 19). However, it seems that the current version of QGC (4.2.0) is built on Qt v5.15.2, which dropped API 19 as minimum SDK version, and now is at 21.

Is there any work around/solution?

Thanks.
