我的CMakeLists.txt中有以下代码段，如wxWidgets wiki中所述

set(wxWidgets_ROOT_DIR libs/wxWidgets)
set(wxWidgets_CONFIGURATION mswu)
find_package(wxWidgets REQUIRED
        COMPONENTS core base adv)
include(${wxWidgets_USE_FILE})

libs/wxWidgets是一个git子模块。在Ubuntu 16.04上，该项目可以构建和运行。该子模块的描述如下：

[submodule "libs/wxWidgets"]
    path = libs/wxWidgets
    url = https://github.com/wxWidgets/wxWidgets
    branch = WX_3_0_3_BRANCH

但是，在Windows上使用相同的代码是行不通的，错误如下：

CMake Error at C:/Program Files (x86)/CMake/share/cmake-3.9/Modules/FindPackageHandleStandardArgs.cmake:137 (message):
      Could NOT find wxWidgets (missing: wxWidgets_LIBRARIES
  wxWidgets_INCLUDE_DIRS)
Call Stack (most recent call first):
  C:/Program Files (x86)/CMake/share/cmake-3.9/Modules/FindPackageHandleStandardArgs.cmake:377 (_FPHSA_FAILURE_MESSAGE)
  C:/Program Files (x86)/CMake/share/cmake-3.9/Modules/FindwxWidgets.cmake:953 (find_package_handle_standard_args)
  CMakeLists.txt:8 (find_package)

尝试从official site安装其他wxWidget，包括zip和Windows Installer，但产生相同的错误。
This question可能相关，但没有可接受的答案。
