使用 WxWidgets 和 Conan 的未定义符号

Question

我正在尝试采用 Conan C++ 包管理器。我跟着入门已经设法让它与大多数项目一起工作。但是我遇到了与 WxWidgets 的链接问题，我似乎无法修复。

链接器错误：

[ 23%] Linking CXX executable ../bin/wx_sample
Undefined symbols for architecture x86_64:
  "Frame::onMenuFileQuit(wxCommandEvent&)", referenced from:
      __GLOBAL__sub_I_frame.cpp in frame.cpp.o

柯南默认配置文件：

Configuration:
[settings]
arch=x86_64
arch_build=x86_64
build_type=Release
compiler=apple-clang
compiler.libcxx=libc++
compiler.version=12.0
os=Macos
os_build=Macos

我不确定是否需要将 dep 包含到我的 conanfile 中，尽管我认为 Conan 会自动管理它？如果我删除错误中列出的违规部分，应用程序链接成功。

编辑： 您在 CONAN_LIBS 全球范围内是正确的。您的 CMake 结构看起来不错。您可以尝试从 src CMakeLists.txt.

调用 conan_basic_setup()

如果这不起作用，问题可能出在您的 conanfile.py 中。 https://github.com/bincrafters/conan-wxwidgets/commit/37b6669229ec0e68593065a700c360d23a914bac
