Only policies 51-54 were added between 3.0 and 3.1. I suggest testing with cmake_minimum_required(VERSION 3.0) cmake_policy(SET CMP0051 NEW) cmake_policy(SET CMP0052 NEW) cmake_policy(SET CMP0053 NEW) cmake_policy(SET CMP0054 NEW) and then trying different combinations. My guess is CMP0054. ------------------------------------------------------------- While looking at the source of that project, I noticed that both `CMakeLists.txt` and `smtk-import/CMakeLists.txt` call the `project()` command before `cmake_minimum_required()`. The other order is preferred: cmake_minimum_required(VERSION 2.8.11) project(Subsurface) because there are policies that affect project()'s behavior. This order preference is documented by both commands. I also noticed this code: ``` # don't process generated files - this is new in 3.10 if (POLICY CMP0071) cmake_policy(SET CMP0071 OLD) endif() ``` The cmake-policies(7) manual states that a policy should only be set to OLD to silence warnings in frozen code bases or in short-term circumstances. The proper way to deal with CMP0071 is to set it to NEW and set the `SKIP_AUTO*` properties on the sources that should not be processed. -Brad -- Powered by www.kitware.com Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Kitware offers various services to support the CMake community.
