c++ - Ninja:安装目标

Question

我已经为我正在处理的 C++ 项目编写了一个 build.ninja 文件。没什么特别的，只是一堆编译并链接到可执行文件中的 C++ 源文件(见下文)

我想添加一个安装目标，它只是将可执行文件复制到/usr/local/games 中。我该如何实现？

cflags = -DSYZYGY -Wall -Wcast-qual -fno-exceptions -fno-rtti  -ansi -pedantic -Wno-long-long $
  -Wextra -Wshadow -DNDEBUG -O3 -DIS_64BIT -msse -DUSE_BSFQ -msse3 -mpopcnt -DUSE_POPCNT -flto
lflags = -lpthread $cflags

rule compile
  command = c++ -MMD -MT $out -MF $out.d $cflags -c $in -o $out
  description = Compiling $in
  depfile = $out.d
  deps = gcc

rule link
  command = c++ -o $out $in $lflags && strip $out
  description = Linking $out

default stockfish

也许这可以解决问题(未经测试):

rule copy
  command = cp $in $out
build /usr/local/games/stockfish: copy stockfish
build install: phony /usr/local/games/stockfish
