question on the compilation database

we’re planning for a tool that generates a clang compilation database from our byzantine build system.

file.gen: file.src
    cp file.src file.gen

exe: file.o
    gcc -o exe file.o

file.o:
[
  { "directory": "/home/user/llvm/build",
    "command": "/usr/bin/clang++ -Irelative -DSOMEDEF=\"With spaces, quotes and \\-es.\" -c -o file.o file.cc",
    "file": "file.cc" },
  ...
]
[
  { "directory": "/home/user/llvm/build",
    "command": "/usr/bin/clang++ -Irelative -DSOMEDEF=\"With spaces, quotes and \\-es.\" -c -o file.o file.cc",
    "file": "file.cc" },
  ...
]
