Hi, Here is the minimal CMakeLists.txt that reproduces the issue: cmake_minimum_required(VERSION 3.22.0) project(mgl_test LANGUAGES CXX) find_package(MathGL2 REQUIRED)
If the packages libomp-dev and libomp-XX-dev that it drags (libomp-11-dev on stable, libomp-14-dev on my testing setup) are not installed I get the initial reported error.
