如何让介子找到我的windres二进制文件？

Question

我正在使用 conan 包管理器在交叉编译设置中构建 freetype 2.13.2（以及其他依赖项）（在 Linux 主机上使用 mingw32）。

我收到以下错误消息

../src/meson.build:239:11: ERROR: Could not find Windows resource compiler

据我了解，介子寻找名为

windres

的二进制文件，而我的二进制文件名为

x86_64-w64-mingw32-windres

。

我如何告诉介子（通过柯南）我的windres二进制文件的名称？

我的柯南命令行是

 conan install .. -pr:b=default -pr:h=windows-cross --build=missing

$ cat ~/.conan/profiles/default
[settings]
os=Linux
os_build=Linux
arch=x86_64
arch_build=x86_64
compiler=gcc
compiler.version=11
compiler.libcxx=libstdc++11
build_type=Release
[options]
[build_requires]
[env]

$ cat ~/.conan/profiles/windows-cross
[settings]
os=Windows
os_build=Linux
arch=x86_64
arch_build=x86_64
compiler=gcc
compiler.version=10
compiler.libcxx=libstdc++11
build_type=Release

$ cat /home/per/mingw-w64-x86_64.cmake
set(CMAKE_SYSTEM_NAME Windows)
set(TOOLCHAIN_PREFIX x86_64-w64-mingw32)

# cross compilers to use for C, C++ and Fortran

# target environment on the build host system
set(CMAKE_FIND_ROOT_PATH /usr/${TOOLCHAIN_PREFIX})

# modify default behavior of FIND_XXX() commands
set(CMAKE_FIND_ROOT_PATH_MODE_PROGRAM NEVER)
set(CMAKE_FIND_ROOT_PATH_MODE_LIBRARY ONLY)
set(CMAKE_FIND_ROOT_PATH_MODE_INCLUDE ONLY)

根据此链接介子默认为环境变量

WINDRES

的值。

所以尝试在环境中设置

WINDRES=x86_64-w64-mingw32-windres

。
