Failing to open `ftxui-screen.lib` on Windows with GitHub Actions & CPM

[szymonj99]

I'm able to compile locally, but my project fails to compile when running with GitHub Actions on windows-latest in either debug or release modes. I am using CPM, but the same has happened when using FetchContent manually.

Error

Generating Code...
LINK : fatal error LNK1181: cannot open input file 'Release\ftxui-screen.lib' [D:\a\...\build\_deps\ftxui-build\dom.vcxproj]

Setup

CPMAddPackage("gh:ArthurSonzogni/FTXUI#764c24ef4046fbfd3cb1a25d0cb8a47a84e82d3a")
...
target_link_libraries(${PROJECT_NAME} PRIVATE ... ftxui::screen ftxui::dom ftxui::component)

ftxui-screen.dll seems to be generated correctly:

Let me know if this is an issue on my end 💯

What's your github action?

There is likely a problem. You can probably take some inspiration from: https://github.com/ArthurSonzogni/FTXUI/blob/764c24ef4046fbfd3cb1a25d0cb8a47a84e82d3a/.github/workflows/build.yaml#L35-L37

My action is as follows (BUILD_TYPE is Release):

build-windows-release:
    runs-on: windows-latest

    steps:
    - uses: actions/checkout@v2

    - name: Configure CMake
      run: cmake -B ${{github.workspace}}/build -DCMAKE_BUILD_TYPE=${{env.BUILD_TYPE}}

    - name: Build
      run: cmake --build ${{github.workspace}}/build --config ${{env.BUILD_TYPE}}

I'll give your suggestion a try and report back. Thanks! 💯

Unfortunately, your suggestion doesn't seem to have worked for me so far. Below is my updated workflow file. Let me know if I missed something 💯
