WIP: FreeFileSync on CentOS 7, part 1

   In my original dev environment, I can now compile and execute the main
   binaries. My next commit should include some attempts at static
   linking so the runtime environment does not need the hacked
   openssl 1.1.0h packages.

+The cstddef discovery is from https://stackoverflow.com/questions/52567517/freefilesync-c-error-byte-is-not-a-member-of-std
+Some changes just make the application work better in an installed setting (e.g., the hard-coded resouce path).
+Tricking the wxWidgets ABI version comes from https://stackoverflow.com/questions/45123664/wxwidgets-runtime-error-mismatch-version/47822976#47822976
