I've been trying to address the following issue in `clangd` for Visual Studio
Code trying to access CUDA:
https://github.com/clangd/clangd/issues/793
This patch alone is not yet sufficient for a fully functional clangd, but it
gets rid of the error message saying
Cannot find CUDA installation. Provide its path via --cuda-path, or pass
-nocudainc to build without CUDA includes.
in case clangd and the code is located on the `C:` drive.
In my case I had both `clangd` (which I needed for debugging purposes) and the
source code on `D:`. At this point:
c++
Candidates.emplace_back(D.SysRoot + "/Program Files/NVIDIA GPU Computing
Toolkit/CUDA/v" + Ver);
the `D.SysRoot` seems to be empty. Then, during the call to
c++
if (InstallPath.empty() || !FS.exists(InstallPath))
after `sys::fs::make_absolute(WD->Resolved, Storage);` (in
`VirtualFileSystem.cpp`) the `Storage` expands to `D:/Program Files/NVIDIA GPU
Computing Toolkit/CUDA/v11.4` which isn't found either.
