Makefile 到 CMakeLists.txt
我在将附加的 Makefile 转换为等效的 CMakeLists.txt 时遇到一些问题。
构建过程如下:
- 使用 flex 给定 src/lexer.l.cpp 生成 src/lexer.cpp。
- 使用 bison 给定 src/parser.y.cpp 生成 src/parser.cpp。
- 将 src/ 中的几乎所有内容编译到 .so 库中。
- 使用不同的标志重新编译它们以生成可执行文件。
在 stdlib/ 目录三内编译源代码,将二进制文件输出到 build/ 以便:
stdlib/std/hashing/md5.cc
会变成
build/std/hashing/md5.so
但我真的不知道如何使用 cmake 宏重现这个过程......有什么帮助吗?

I have some problems converting the attached Makefile to an equivalent CMakeLists.txt .
The build process goes like that :
- Generate src/lexer.cpp given src/lexer.l.cpp with flex.
- Generate src/parser.cpp given src/parser.y.cpp with bison.
- Compile almost anything inside src/ into a .so library.
- Recompile them with different flags to generate an executable.
Compile sources inside stdlib/ directories three, output the binaries to build/ so that :
stdlib/std/hashing/md5.cc
Would become
build/std/hashing/md5.so
But i really don't know how to reproduce this process with cmake macros ... any help ?

对于 flex/bison 部分(警告:未经测试,我通常为解析器+词法分析器文件添加 .ypp 和 .lpp 后缀):
For the flex/bison part (warning: untested, I usually have .ypp and .lpp suffixes for parser+lexer files):
