I would need more details of the install process to understand what is going on. I see you're running under Fedora. In this case, v2.0.0 should look first for an existing NLopt build on your system of recent enough version (>= 2.7.0) and use it if found. In case it cannot find such a build, it should build NLopt from included sources using cmake. In this case, it will attempt to find cmake binary on your PATH and, if it cannot find it, it should prompt you to install it suggesting a variety of options. I don't see this message in the error you shared here. Can you please detail?

You are right. After installing cmake, the problem is gone. Thanks.
