c++ - 使用 wxMac 在 OSX 上构建 wxWidgets wxWebView 失败

Question

我正在尝试在 OSX 上使用 wxWebView 构建一个简单的 C++ Web 窗口。我正在使用来自 HomeBrew 的 wxMac 安装。构建未能找到必要的重写类来处理本机 wxWebView。结果是 wxWebView 未定义。

error: unknown type name 'wxWebView'; did you mean 'WebView'?
  wxWebView *foo = nullptr;

webview被封装在一个wxDialog消息中，如下：

这是我的 wxMac 安装版本信息：

wxmac: stable 3.0.5 (bottled), HEAD
Cross-platform C++ GUI toolkit (wxWidgets for macOS)
https://www.wxwidgets.org
/usr/local/Cellar/wxmac/3.0.4_2 (810 files, 22.9MB) *
  Poured from bottle on 2020-01-17 at 06:48:37
From: https://github.com/Homebrew/homebrew-core/blob/master/Formula/wxmac.rb

从 Homebrew repo 中的 ruby​​ 脚本来看，wxWidgets 似乎是在为 OSX 启用 wxWebView 的情况下构建的。我正在使用以下 CMake 片段来构建它：

set (VizSrcs
IRVizWin.cpp
)
find_package(wxWidgets COMPONENTS net adv aui core gl html propgrid qa ribbon richtext stc xrc base webview REQUIRED)
IF(wxWidgets_FOUND)
  INCLUDE("${wxWidgets_USE_FILE}")
  include_directories ( . )
  message(STATUS " wxWidgets Include: ${wxWidgets_INCLUDE_DIRS}")
  include_directories (${wxWidgets_INCLUDE_DIRS})
  add_library(VizObjs OBJECT ${VizSrcs})
ELSE(wxWidgets_FOUND)
  MESSAGE("wxWidgets not found!")
ENDIF(wxWidgets_FOUND)

HomeBrew下的wxMac是否支持wxWebView？如果是这样，我错过了什么？
