CMake Error at .*Modules/WriteCompilerDetectionHeader.cmake:[0-9]+ \(message\): CMake Error at .*Modules/WriteCompilerDetectionHeader.cmake:[0-9]+ \(message\):
VERSION parameter too low. VERSION compatibility for write_compiler_detection_header is set to 3.0,
which is too low. It must be set to at least 3.1.0. Either set the
VERSION parameter to the write_compiler_detection_header function, or
update your minimum required CMake version with the cmake_minimum_required
command.
