CMake WxWidgets项目在linux上成功构建但在windows上没有

Question

我已经设法在 Ubuntu 19.10 上基于 CMake 构建了一个 WxWidgets，但在 Windows 10 上失败了，说它找不到 WxWidgets，尽管我已经成功构建了它（静态、发布并支持 unicode）。

WxWidgets 路径为C:\wxWidgets-3.1.3，构建目录为C:\wxWidgets-3.1.3\msw-release。

makefile 是

cmake_minimum_required(VERSION 3.0)

project(ChessPgnReviser VERSION 0.1.0)

set(CMAKE_CXX_STANDARD 11)
set(CMAKE_CXX_STANDARD_REQUIRED ON)

ADD_DEFINITIONS(-Wall -Wno-sign-compare -O2)

set(SRCS
    src/main.cpp
)

set (HEADERS
)

message( "--Root--" ${wxWidgets_ROOT_DIR} )
message( "--Lib dir--" ${wxWidgets_LIB_DIR} )

add_executable(ChessPgnReviser ${SRCS} ${HEADERS})

find_package(wxWidgets COMPONENTS net gl core base)
if(wxWidgets_FOUND)
  include(${wxWidgets_USE_FILE})
  target_link_libraries(ChessPgnReviser ${wxWidgets_LIBRARIES})
else()
    message(FATAL_ERROR "Failed to find WxWidgets library")
endif()

我正在使用 Msys 64 位来编译项目。在其子文件夹 etc/profile 的底部，我添加了

PATH=$PATH:/c/dev/cmake/bin
wxWidgets_ROOT_DIR=/c/wxWidgets-3.1.3
wxWidgets_LIBRARIES=$wxWidgets_ROOT_DIR/msw-release/lib
wxWidgets_LIB_DIR=$wxWidgets_ROOT_DIR/msw-release/lib
wxWidgets_INCLUDE_DIRS=$wxWidgets_ROOT_DIR/include

所以我试过了

$ mkdir build && cd build

另外，感谢@squareskittles，我也试过了：

$ cmake .. -G "MinGW Makefiles" -DwxWidgets_ROOT_DIR="C:\wxWidgets-3.1.3" -DwxWidgets_LIB_DIR="C:\wxWidgets-3.1.3\msw-release\lib"

您可以找到 msw-release 文件夹的内容：there。

还有：

$ ls /c/wxWidgets-3.1.3/msw-release/lib/
libwx_baseu_net-3.1.a  libwx_baseu-3.1.a     libwx_mswu_aui-3.1.a   libwx_mswu_gl-3.1.a    libwx_mswu_media-3.1.a     libwx_mswu_qa-3.1.a      libwx_mswu_richtext-3.1.a  libwx_mswu_webview-3.1.a  libwxregexu-3.1.a     wx
libwx_baseu_xml-3.1.a  libwx_mswu_adv-3.1.a  libwx_mswu_core-3.1.a  libwx_mswu_html-3.1.a  libwx_mswu_propgrid-3.1.a  libwx_mswu_ribbon-3.1.a  libwx_mswu_stc-3.1.a       libwx_mswu_xrc-3.1.a      libwxscintilla-3.1.a

那我是不是忘记了什么？

要正确检测 wxWidgets，您需要 wx-config。

存在wx-config 的 Windows 版本，可从以下位置下载：https://github.com/kowey/wx-config-win

要让wx-config知道你的wxWidgets在哪里，你需要设置以下环境变量：

• WXWIN（你的情况是C:/wxWidgets-3.1.3）
• WXCFG（在你的情况下是like msw/gcc_mswu）。
