VSCode Intellisense does not find headers of packages installed with vcpkg (WSL2)

[pfuerste]

I am pretty new to CMake and just installed some packages via vcpkg. Am I missing something? I used vcpkg to install some package for my project, but intellisense tells me it cant open the source file:

This are the 3 items in my includepath:

${workspaceFolder}/** ~/vcpkg/installed/x64-linux/ ~/vcpkg/installed/x64-linux/**

CMake does find the files of the installed packages after set(CMAKE_PREFIX_PATH "~/vcpkg/installed/x64-linux/") and is able to compile.

You're using the CMake Tools configuration provider? Did you run CMake: Configure? Can you look at the output of running C/C++: Log Diagnostics and look for what includes paths are being sent by the configuration provider? This may be a CMake Tools bug (includePath won't get used if CMake Tools is used)

[pfuerste]

Thanks for your answer. I did not configure at first, but did now, the error remains the same. I had the CMake and CMake Tools extensions installed, but did not actually use them yet (my project structure is rather simple and I wanted to get into the extensions soon). Uninstalling them fixed the problem.

Edit: After a restart, the problem came back. I currently do NOT have the CMake (&Tools) Extensions installed in WSL, but I do get the error. The strange thing is, Intellisense (or at least I guess its Intellisense) does autocomplete the path while tying, but gives me red squiggles afterwards.

It also autocompletes from the imported libraries, such as cv::Vec3b, but still squiggles it.

I hope this is the right output for the Log diagnostics you asked for:

[sean-mcmanus]

Can you run C/C++: Log Diagnostics from the View->Command Palette?

The logging you provided suggests that /vcpkg/installed/x64-linux/include is in your include path. Where is the catch2 folder located? You'll want to make sure that folder is in your include path. If you think that the "**" recursive includes is not finding the path when it should be, you can try running the C/C++: Reset IntelliSense Database command.

[pfuerste]

catch.hpp is in ~/vcpkg/installed/x64-linux/include/catch2 and ~/vcpkg/installed/x64-linux/include/** is currently in my include path, so it should find it, right? I did reset the Database, which did not help.

Here is the Log Diagnostics output:

You have configurationProvider set, which will cause includePath to not be used. Can you remove that?

[pfuerste]

Yeah, that fixed it. I don't know why it was set though (or what it is), will this impact other functionality?

[sean-mcmanus]

There are some code paths that may auto-set that or in response to a prompt button if we detect that you have CMake Tools installed and have a CMakeLists.txt. If you're using a CMake project, it usually recommended to be configured via the CMake Tools configuration provider, but if your project is simple enough you can configure it via c_cpp_properties.json as well. It shouldn't affect anything except how IntelliSense is getting its configuration information.
