解决的办法：

这段信息表明用户尝试在他们的环境中安装一个Python项目，但是在构建过程中出现了错误。具体来说，当pip尝试为 rtmp-streaming 这个项目构建一个轮子（wheel，是Python的二进制包格式）时，构建失败了。失败的原因是 python setup.py bdist_wheel 命令没有成功执行。错误信息指出，在运行构建扩展（build_ext）的过程中出错了，错误信息是 “No such file or directory: ‘cmake’”。

cmake 是一个常用的跨平台自动化构建系统，用于管理软件构建过程，它在这个过程中需要用到。错误表明 cmake 没有在执行命令的环境中找到，这通常意味着 cmake 没有安装在系统上，或者没有被添加到PATH环境变量中。

要解决这个问题，用户需要确保 cmake 已经正确安装并且系统可以找到它。在Ubuntu系统上，可以通过以下命令来安装 cmake：

sudo apt-get update
sudo apt-get install cmake

安装完成后，用户可以重新运行pip安装命令来尝试再次构建项目。如果问题仍然存在，可能需要检查项目的构建脚本或者与项目维护者联系以获得进一步的帮助。
