Hello,

I am using GitHub Actions for my open-source project: [GitHub - matwey/libopenvizsla at github-actions](https://github.com/matwey/libopenvizsla/tree/github-actions)  
While trying to fix the build for Windows, I’ve faced an issue which I could not reproduce in my environment.  
Both environments uses cmake 3.23, and same vcpkg versions are in use. However the environments produce different `vcxproj` files for the same `CMakeLists.txt`.

Critical difference that cmake at GitHub doesn’t use include paths for the resource compiler while local cmake does:

```auto
     <ResourceCompile>
       <PreprocessorDefinitions>%(PreprocessorDefinitions);WIN32;_WINDOWS;NDEBUG;_XOPEN_SOURCE;_XOPEN_SOURCE_EXTENDED;CMAKE_INTDIR=\"Release\";openvizsla_EXPORTS</PreprocessorDefinitions>
- <AdditionalIncludeDirectories>D:\a\libopenvizsla\libopenvizsla\include;D:\a\libopenvizsla\libopenvizsla\build;%(AdditionalIncludeDirectories)</AdditionalIncludeDirectories>
+ <AdditionalIncludeDirectories>C:\Users\User\libopenvizsla\include;C:\Users\User\libopenvizsla\build;C:\Users\User\vcpkg\installed\x64-windows\include\libusb-1.0;C:\Users\User\vcpkg\installed\x64-windows\include\libftdi1;C:\Users\User\vcpkg\installed\x64-windows\include;%(AdditionalIncludeDirectories)</AdditionalIncludeDirectories>
     </ResourceCompile>

```

This leads to resource compilation failure due to required header file cannot be opened.

Include paths for comping the code are file in both cases:

```auto
     <ClCompile>
- <AdditionalIncludeDirectories>C:\vcpkg\installed\x64-windows\debug\lib\pkgconfig\..\..\..\include\libusb-1.0;C:\vcpkg\installed\x64-windows\debug\lib\pkgconfig\..\..\..\include\libftdi1;C:\vcpkg\installed\x64-windows\debug\lib\pkgconfig\..\..\..\include;D:\a\libopenvizsla\libopenvizsla\include;D:\a\libopenvizsla\libopenvizsla\build;%(AdditionalIncludeDirectories)</AdditionalIncludeDirectories>
+ <AdditionalIncludeDirectories>C:\Users\User\libopenvizsla\include;C:\Users\User\libopenvizsla\build;C:\Users\User\vcpkg\installed\x64-windows\include\libusb-1.0;C:\Users\User\vcpkg\installed\x64-windows\include\libftdi1;C:\Users\User\vcpkg\installed\x64-windows\include;%(AdditionalIncludeDirectories)</AdditionalIncludeDirectories>
       <AssemblerListingLocation>$(IntDir)</AssemblerListingLocation>
       <DebugInformationFormat>ProgramDatabase</DebugInformationFormat>
       <ExceptionHandling>
@@ -272,10 +272,10 @@
     </ClCompile>

```

How could I debug this issue further? Because I have no idea what could be wrong here.

One machine seems to have `../` in those paths. There are situations that can confuse CMake in the presence of junctions or reparse points. Are you sure the vcpkg environments are the same on these two machines?

Thank you. Your hint was very helpful. I think I’ve found the difference. GitHub actions has pkg-config installed. My `CMakeLists.txt` supports both `pkg-config` for UNIX systems and fallback to `find_library` for Windows. However, `pkg-config` produces unnormalized paths on Windows.

In that case, it might be that `pkg-config` is causing the GHA instance to go down some wrong assumptions about installation layouts and such. You can either update how you find your dependencies (i.e., not assume that `pkg-config` is the best way if it exists) or make it support whatever `vcpkg` is doing with `.pc` files here.

Why does `ClCompile` understand this paths while `ResourceCompile` doesn’t? Isn’t this should be fixed inside CMake?

🤷 `rc.exe` is a different tool from `cl.exe`. I can’t speak to why one might interpret paths differently than the other.
