Ubuntu 20.04：Cmake 错误：找不到 ALSA（缺少：ALSA_LIBRARY ALSA_INCLUDE_DIR）

Ubuntu 20.04：Cmake 错误：找不到 ALSA（缺少：ALSA_LIBRARY ALSA_INCLUDE_DIR）

cmake当我尝试编译 Buildroot 系统时出现了奇怪的错误。

由于 hello 包不需要 ALSA，因此 cmake 在检查 ALSA 是否存在时似乎崩溃了。我已经安装了libasound2和libasound2-dev。

我自己编译过cmake（安装 ALSA 库后重复了步骤），但没有变化。有什么建议，可以帮忙解决这个问题吗？

用于sudo apt-get install libasound2-dev安装缺少的软件包。
