我一直在尝试从依赖于 libxml2 的 Linux > Windows 交叉编译应用程序。我正在尝试使用 Conan 来管理依赖项。
我一直遇到各种障碍，当前的问题是 libxml2 似乎无法找到自己的标头。
首先，找不到生成的config.h头文件：
x86_64-w64-mingw32-gcc -m64 -O3 -DNDEBUG -I/home/robert/.conan/data/libiconv/1.17/_/_/package/c6817f477abe7e9a917b102f37dc1fd0c2d95f50/include -I/home/robert/.conan/data/zlib/1.2.13/_/_/package/c6817f477abe7e9a917b102f37dc1fd0c2d95f50/include -DWIN32 -m64 -L/home/robert/.conan/data/libiconv/1.17/_/_/package/c6817f477abe7e9a917b102f37dc1fd0c2d95f50/lib -L/home/robert/.conan/data/zlib/1.2.13/_/_/package/c6817f477abe7e9a917b102f37dc1fd0c2d95f50/lib /home/robert/.conan/data/libxml2/2.10.3/_/_/build/6a818f7d8bbba2942e1499f2d61557299d4122bd/src/xmllint.c -o xmllint

我尝试手动将它复制到源文件夹中，但这只会导致它在另一个标题上失败：

这是我的conanfile：
from conans import ConanFile, CMake, tools
class SomethingConan(ConanFile):
name = "something"
version = "0.1.0"
settings = "os", "compiler", "build_type", "arch"
requires = "zlib/1.2.13", "libxml2/2.10.3", "zstd/1.5.4"
options = {"mode": ["tests", "qt"]}
generators = "cmake"
def build(self):
cmake = CMake(self)
cmake.configure(source_folder="src")
cmake.build()
我的个人资料基于柯南文档中的指南之一：
toolchain=/usr/x86_64-w64-mingw32 # Adjust this path
target_host=x86_64-w64-mingw32
cc_compiler=gcc
cxx_compiler=g++

RANLIB=$target_host-ranlib

CXX=$target_host-$cxx_compiler
STRIP=$target_host-strip
RC=$target_host-windres
[settings]
# We are cross-building to Windows

compiler=gcc

arch_build=x86_64
build_type=Release
# Adjust to the gcc version of your MinGW package
compiler.version=10
compiler.libcxx=libstdc++11
build_type=Release
我正在尝试安装依赖项：
conan install -pr:h mingw.profile -s:b os_build=Linux -o mode=qt --build=missing .
我正在使用柯南 1.59.0。我尝试使用 Conan 2，但我找不到任何关于从 Linux > Windows 与 Conan 2 交叉编译的有用文档。mingw 版本是 apt 的 10.3.0-14。
谁能看出我做错了什么？
