ostinato build issues with Qt5.15.2 MinGW 32-bit.

You need to build libprotobuf for Windows yourself and set the CPLUS_INCLUDE_PATH and LIBRARY_PATH env vars appropriately as given in the Build Instructions

Or you might skip all that and buy the pre-packaged Ostinato for Windows installer directly which is much more easier :-D

Please share the full build log.

FYI, the build instructions are at https://devguide.ostinato.org/build-instructions/
