在 Windows 中使用 MinGW 作为 tool_requires 用 gcc 构建

如果我们在环境中安装了 MinGW，我们可以定义一个类似这样的配置文件：

[settings]
os=Windows
compiler=gcc
compiler.version=12
compiler.libcxx=libstdc++11
compiler.threads=posix
compiler.exception=sjlj
arch=x86_64
build_type=Release

[buildenv]
PATH+=(path)C:/path/to/mingw/bin
# other environment we might need like
CXX=C:/path/to/mingw/bin/g++
# etc

[conf]
# some configuration like 'tools.build:compiler_executables' might be needed for some cases

但我们也可以使用包含 MinGW 编译器副本的 Conan 包，并将其用作 tool_requires

mingw-profile.txt
[settings]
os=Windows
compiler=gcc
compiler.version=12
compiler.libcxx=libstdc++11
compiler.threads=posix
compiler.exception=seh
arch=x86_64
build_type=Release


[tool_requires]
mingw-builds/12.2.0

使用此配置文件，我们可以在 Windows 中例如创建如下包：

# Using a basic template project
$ conan new cmake_lib -d name=mypkg -d version=0.1
$ conan create . -pr=mingw
...
-- The CXX compiler identification is GNU 12.2.0
...
