获得代码：
git clone https://bitbucket.org/mituharu/emacs-mac.git阅读 INSTALL.REPO ，要求安装
- autoconf
- git
- makeinfo
macOS 已经自带了 git 和 makeinfo，只需要安装 autoconf
brew install autoconf生成 configure：
./autogen.sh配置：
./configure --with-modules报错：
configure: error: The following required libraries were not found: gnutls Maybe some development libraries/packages are missing? If you don’t want to link with them give –with-gnutls=no as options to configure
重新配置：
./configure --with-modules --with-gnutls=no编译：
make测试；
open -n mac/Emacs.app --args -Q问题：

安装 gnutls
brew install gnutls重新配置
./configure --with-modules依旧包找不到 gnutls
configure: error: The following required libraries were not found: gnutls Maybe some development libraries/packages are missing? If you don’t want to link with them give –with-gnutls=no as options to configur
安装 pkg-config (Homebrew 的 emacs 需要这个)
brew install pkg-config重新配置
./configure --with-modules安装
make测试 HTTPS，正常
(eww "https://emacs-china.org")安装的所有包
brew ls其中 autoconf gnutls pkg-config 是主动安装的，其余的都是依赖
