I would like to enable intellisense for my C++ project that is being built with bazel in VS code.
There used to be a an extension that could do it, but it has been discontinued since the release of the official vscode-bazel extension which lacks this ability.
There is an open issue on vscode-bazel regarding this feature.
Fortunately, somebody pointed to an other tool bazel-compilation-database which can automatically generate a compile_commands.json.
Once you have generated that file, add it to your .vscode/c_cpp_properties.json file by adding the line
"compileCommands": "${workspaceFolder}/compile_commands.json"
Intellisense should now be enabled assuming you have vscode-cpptools extension installed.
