Target "tinyxml2" of type OBJECT_LIBRARY may not be linked into another target.

CMake Error at tests/xmltester/CMakeLists.txt:30 (target_link_libraries):
  Target "tinyxml2" of type OBJECT_LIBRARY may not be linked into another
  target.  One may link only to STATIC or SHARED libraries, or to executables
  with the ENABLE_EXPORTS property set.

Marking it as having Severity = Critical because it worked just fine with autotools but autotools have been removed from master branch, so I basically cannot build anymore until this is fixed.

It looks like changes ( 3dd7121 ) I introduced to quiet compiler warnings in vendored libraries require CMake 3.13. So this can be solved either by updating cmake_minimum_required to 3.13, or reverting those changes and accepting that we cannot use -Werror because of warnings from vendored libraries.

Please lower the requirement, lowering entry barrier for devs

Reverting merge commit 3dd7121 (picking parent index 1) seems to fix the error (but reverts a lot of things)

In f65bb35/git:

Use OBJECT library to build ryu, so it can be fully included in
static libgeos.a, and up the cmake requirement to 3.13 to support
that change. References #1103
