需要下载 11.1 MB 的归档。
解压缩后会消耗 41.1 MB 的额外空间。
您希望继续执行吗？ [Y/n]

有时还得再装extra-cmake-modules呢，这个倒是小：需要下载198 kB，解压后会消耗841 kB.

# apt install meson
将会同时安装下列软件：ninja-build
下列【新】软件包将被安装：meson ninja-build
需要下载 683 kB 的归档。
解压缩后会消耗 3,968 kB 的额外空间。

Ninja joins a sea of other build systems. Its distinguishing goal is to be fast. It is born from the Chromium browser project, which has over 30,000 source files and whose other build systems can take ten seconds to start building after changing one file. Ninja is under a second. 

Ninja文件应通过其他程序（如CMake, Meson）生成，呵呵。cc -c a.cc; cc *.o岂不更快？
