Compilation fails with gtest-death-test.cc

[timlinux]

Following the steps in https://github.com/MerginMaps/mergin-db-sync#installation to compile geodiff I get this error:

hi @timlinux is it possible that you had this build directory from some earlier times? It looks like it is using some older version of GTest library - please try to do a clean build, that should help!
