I remember around cmake v3.6, the behavior of enable_language() changed so that if you did it too many times, you'd get the error:
Language 'C' is currently being enabled. Recursive call not allowed. I need to implement some backward compatibility code to check of CMake version less than 3.6 (or appropriate version), then still call enable_language(), otherwise do not call it. Is 3.6 the correct version in which this behavior was introduced? -- 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.
