我尝试在Centos 7上编译Emacs 26.2
./configure
但是脚本抱怨：
configure: error: The following required libraries were not found:
gnutls
Maybe some development libraries/packages are missing?
yum告诉我gnutls已经安装：
Package gnutls-3.3.29-9.el7_6.x86_64 already installed and latest version
我还错过了用Gnutls支持编译Emacs的什么？
尝试安装软件包gnutls-devel。虽然gnutls软件包包含使用Gnutls的程序所需的文件，而gnutls-devel则需要用于使用Gnutls的程序 compile 。
