求助：使用Conan交叉编译libxml2（Linux→Windows）遇头文件问题

我在Linux环境下，用Conan管理依赖，交叉编译一个依赖libxml2的Windows应用，核心问题是libxml2无法找到自身头文件：

第一个错误：找不到config.h #

编译时提示如下错误：

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

第二个错误：手动复制config.h后找不到libxml/xmlversion.h #

尝试手动将config.h复制到源码目录后，出现新错误：

请问我哪里操作有误？
