This reverts commit 80a25bcd3021f7ebfaf2f864e34532009b9b8aeb. It didn't really make sense to do all those changes in the same MR partially Revert "Store refactoring: more forgotten storeSpecialization.hpp" This reverts commit 9943a5bc96b9025f06cbaac5bb7f1bf51ebc746f. removed remaining references to storeSpecialization CMakeLists.txt, and landmanager.cpp
