VSCode 'cannot open source file "boost/serialization/serialization.hpp" (dependency of "mlpack/core.hpp")' when trying to include mlpack

Question

I am trying to use mlpack in VSCode. I have installed the library using brew, and have included the path in c_cpp_properties.json:

{
    "configurations": [
        {
            "name": "Mac",
            "includePath": [
                "${workspaceFolder}/**",
                "/opt/homebrew/Cellar/mlpack/3.4.2_2/include"
            ],
            "defines": [],
            "macFrameworkPath": [
                "/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX.sdk/System/Library/Frameworks"
            ],
            "compilerPath": "/usr/bin/clang",
            "cStandard": "c11",
            "cppStandard": "c++17",
            "intelliSenseMode": "macos-clang-arm64"
        }
    ],
    "version": 4
} 

However, when I try and include core.hpp, I get the following error:

cannot open source file "boost/serialization/serialization.hpp" (dependency of "mlpack/core.hpp")C/C++(1696)

Does anyone know how to resolve this? It's my understanding that brew handles the dependencies, is this wrong?

Here is my current tasks.json:

{
    "version": "2.0.0",
    "tasks": [
        {
            "type": "cppbuild",
            "label": "C/C++: clang++ build all files",
            "command": "/usr/bin/clang++",
            "args": [
                "-std=c++17",
                "-stdlib=libc++",
                "-g",
                "${workspaceFolder}/src/*.cpp",
                "--include-directory=/opt/homebrew/Cellar/mlpack/3.4.2_2/include",
                "--include-directory=/opt/homebrew/Cellar/boost/1.75.0_3/include",
                "--include-directory=/opt/homebrew/Cellar/armadillo/10.4.1_1/include",
                "-o",
                "${workspaceFolder}/build/app",
                "-larmadillo",
                "-lmlpack"
            ],
            "options": {
                "cwd": "${workspaceFolder}"
            },
            "problemMatcher": [
                "$gcc"
            ],
            "group": {
                "kind": "build",
                "isDefault": true
            },
            "detail": "compiler: /usr/bin/clang++"
        }
    ]
}

Edit: if I add paths for boost and armadillo:

"includePath": [
                "${workspaceFolder}/**",
                "/opt/homebrew/Cellar/mlpack/3.4.2_2/include",
                "/opt/homebrew/Cellar/boost/1.75.0_3/include",
                "/opt/homebrew/Cellar/armadillo/10.4.1_1/include"
            ],

the error becomes:

'mlpack/core.hpp' file not found

Answer 1

In includePath just add this:

"/opt/homebrew/opt/boost/include"
