I am building this Gtkmm3 application in Ubuntu and wanted to explore GSettings. All was going well while following the instructions at the 'Using GSettings' page and then it was time to configure the make files. I use Eclipse 2019-12 IDE with CDT (V9.10) and 'GNU Make Builder' as the builder. I'm totally perplexed as to how to introduce the macros listed in the GNOME page into the make files. I even tried changing the project to a 'C/C++ Autotools Project' using Eclipse but still the necessary make files to add the macros were missing. Creating a new project with GNU Autotools does create the necessary make files but I was not able to get pkg-config to work with it.
Can anyone point me to some resource which explains how to compile the schema and how & where to load the resultant binary file (externally if necessary). I'll consider myself blessed if someone has already made a Gtkmm3 C++ application with GSettings support using Eclipse IDE in Linux and can share the details.
