[PROJ] proj.db in a cross compilation

[Even Rouault]

Hi Javier,

the "key" is to have a sqlite3 executable for the host architecture 
(that you can point to with the EXE_SQLITE3 CMake variable), and the 
libsqlite3 library for the target one.

For example the GDAL CI has an Android setup at 
https://github.com/OSGeo/gdal/blob/master/.github/workflows/android_cmake/start.sh#L45 
(note that is likely not the most canonical way of setting up an Android 
cross compilation, but at least it works...)
