wxwidgets installed but not detected by FindwxWidgets.cmake

[slodki]

wxWidgets installed with simple vcpkg install wxwidgets:x64-windows-static without problems.
Simple minimal CMake project

cmake_minimum_required(VERSION 3.12)
project(test)
find_package(wxWidgets REQUIRED
    COMPONENTS core qa html xml aui adv stc webview base scintilla)

generates error:

I created a slightly modified FindwxWidgets.cmake, which I placed in vcpkg/ports/wxwidgets/Modules, but I don't know where to fix the CMAKE_MODULE_PATH globally, so that cmake prefers this file over the default FindwxWidgets.cmake.

It works when modifying CMAKE_MODULE_PATH in the project, which calls find_package(wxWidgets MODULE REQUIRED), but I want to change CMAKE_MODULE_PATH from vcpkg.

I tried modifying the CMAKE_MODULE_PATH inside the portfile.cmake, but this didn't work.
The CMAKE_MODULE_PATH was still empty in my project.

this is what I tried to add in the https://github.com/Microsoft/vcpkg/blob/master/ports/wxwidgets/portfile.cmake :
list(APPEND CMAKE_MODULE_PATH "${CMAKE_CURRENT_LIST_DIR}/Modules")

[fei4xu]

Same issue here.
@markusobi Did you find a workaround in the end?

[markusobi]

Same issue here.
@markusobi Did you find a workaround in the end?

No, I ended up putting list(APPEND CMAKE_MODULE_PATH "${_VCPKG_ROOT_DIR}/ports/wxwidgets/Modules") before the find_package(wxWidgets) call on the client side.

The whole wxwidgets build system is a mess.

[zelid]

The same issue, @markusobi can you please share the modified vcpkg aware version of FindwxWidgets.cmake ?

[CaeruleusAqua]

My solution:
https://github.com/CaeruleusAqua/vcpkg-wx-find
(does not work with visual studio generator) -> use ninja

[markusobi]

@zelid
I couldn't find a solution that works on linux too.

[HenryAWE]

It seems that I have the same issue.
Visual Studio solution works well on computer, but the cmake can't find the package when I use cmake to build the executable.

[Censacrof]

I'm having this issue too. I'm making a cross-platform project and I'd like to be able to use cmake on all platforms (Linux, Windows, Mac). Has anyone found a solution to this problem?

[jonathanverner]

I just stumbled into this too :-(

[jmkerloch]

Any update on this issue ? vcpkg is really useful but if we can't use it with wxWidgets there is no point in using it in our projects.

Could you share with us the modified FindwxWidgets.cmake ?

[nickoe]

@jmkerloch I am using this version, slightly modified from what the original author did, see the revisions on the gist.

https://gist.github.com/nickoe/d3c224a2587eff8ea959bc383a993520/

I am not exactly sure why this special findwxwidgets cmake file is needed, it would be nice if a fix could be upstreamed in cmake or vcpkg.

[jmkerloch]

@nickoe I just tried your file and now I can find wxWidgets from VCPKG. Thanks !

I tried that but I got lots of linker errors: https://pastebin.com/xCGEJLLc

[jmkerloch]

@SeanOMik How did you link to wxWidgets in your CMakeList.txt ?

[SeanOMik]

@SeanOMik How did you link to wxWidgets in your CMakeList.txt ?

This is how I find it:

find_package(wxWidgets 3.1 COMPONENTS core base REQUIRED)

And link:

target_link_libraries(discord_client PRIVATE ${wxWidgets_LIBRARY})

[brad-anderson]

I've updated the patch @nickoe did for the latest version of FindwxWidgets.cmake (CMake 3.17.2).

https://gist.github.com/brad-anderson/876a8c581abf285dd20b3c532bf48bd2

[jmkerloch]

@brad-anderson how do you integrate your FindwxWidgets.cmake on your CMakeList.txt ?

The file is working for a release version in Windows but for debug version the path to the .lib are not correct

For example here is the lib include for net module
<vcpkg_root>\installed\x64-windows\lib\wxbase31u_net.lib instead of <vcpkg_root>\installed\x64-windows\debug\lib\wxbase31ud_net.lib

Does anyone have an idea how to get the correct path ?

[jmkerloch]

For the debug version I wasn't selecting the correct version in Visual Studio...
But for linux wxWidgets can be install but is not found with updated FindwxWidgets.cmake

[myirci]

Hi, I also have a similar issue.
I can build wxWidgets (3.1.4) projects from VS 2019 using the installed libraries with vcpkg (both with dynamic and static linking: x64-windows and x64-windows-static) but with cmake (3.18.1) I could not figure out how to do that. find_package always fails and complains about missing: wxWidgets_LIBRARIES.

Is there any progress on this issue?
Thanks!

[LilyWangL]

I will confirm and fix this issue soon.

[JCBurnside]

can confirm that this is still broken at this point in time.

[gvcallen]

Also broken for me.

[gvcallen]

Any temporary fix for this please? Running Windows

[gvcallen]

Using this patch in CMAKE https://gist.github.com/brad-anderson/876a8c581abf285dd20b3c532bf48bd2 I am able to find wxWidgets but get loads of linking errors on Windows

[alvarogalloc]

Did anyone find out how to do it?, or a solution will be merged to master?

[PhoebeHui]

PR #13361 would address this issue.

[fedapo]

This issue seems closed as of today, but I can't still build a basic wxWidgets project with CMake under Linux. Just for the record, the same CMake project builds ok when using the wxWidgets libraries from the Linux distro (Ubuntu 20.04) instead of vcpkg. The only catch is that this line is required in CMakeLists.txt:

include(${wxWidgets_USE_FILE})

This is not indicated in the message provided at the end of the installation of wxWidgets in vcpkg, which reads:

> ./vcpkg install wxwidgets

...

The package wxwidgets provides CMake integration:

    find_package(wxWidgets REQUIRED)
    target_include_directories(main PRIVATE ${wxWidgets_INCLUDE_DIRS})
    target_link_libraries(main PRIVATE ${wxWidgets_LIBRARIES})

A note for those who are stuck: make sure your CMake build matches the --triplet you used when you ran vcpkg install wxwidgets.

A note for those who are stuck: make sure your CMake build matches the --triplet you used when you ran vcpkg install wxwidgets.

This goes without saying, unrelated to wxWidgets.

There have been significant improvements in the past months, including basic CI testing of find_package(wxWidgets).
However, linux support is still incomplete, due to lack of gtk3 in vcpkg (and lack of gtk4 support in wxWidgets).

[EvanBalster]

Running into this same issue. CMake isn't able to locate a x64-windows-static build of wxWidgets while configuring a Visual Studio x64 project.

@drinkitup777 A note for those who are stuck: make sure your CMake build matches the --triplet you used when you ran vcpkg install wxwidgets.

I'm building a small executable utility so I don't know how I can match the -static part of the triplet other than declaring set(wxWidgets_STATIC ON) before find_package(wxWidgets ...

[dg0yt]

@EvanBalster Please open a new new issue, following the current issue templates. There is just too much change in wxwidgets between 2018 and 2022. Again: CMake usage (from a user perspective) is tested in vcpkg CI.

The present of September 2022

• English
  The problem has been solved, but there seems to be a small problem. Especially on VS 2022, you need to manually configure VCPKG_TARGET_TRIPLET to correspond to the platform information, such as x64-windows-static.

• 中文
  这个问题已经解决了，但是瞅着似乎还有一点小问题。尤其是在VS 2022上，需要手动配置一下VCPKG_TARGET_TRIPLET，改为对应平台信息，例如x64-windows-static。
