cannot open source file in VSCode on Linux (ms-vscode.cpptools)

So I ran into this error today when working with GTK-3.0, Linux seems to be confused about how to include header files, because normally I'd use #include <gtk/gtk.h> but because that doesn't work I have to add <gtk-3.0/gtk/gtk.h>. This is what my c_cpp_properties.json file looks like.

Adding /usr/include/gtk-3.0 seemed like a solution, but because gtk.h is dependent on other libraries I have to find out how I can make VSCode look for files recursively. I already tried /usr/local/include/* but with no success.

{
    "configurations": [
        {
            "name": "Linux",
            "defines": [],
            "includePath": [
                "/usr/local/include",           
            ],
            "compilerPath": "/usr/bin/gcc",
            "cStandard": "c11",
            "cppStandard": "c++14",
            "intelliSenseMode": "clang-x64"
        }
    ],
    "version": 4 }

The pkg-config command is usually used to determine all the dependancies and flags needed.

The output of pkg-config --cflags gtk+-3.0 should give you all the compiler flags and pkg-config --libs gtk+-3.0 all the linker flags.

pkg-config also has a --static flag if you need static linking (which requires more dependancies to be linked) and a --msvc-syntax flag to generate MSVC-style flags.

Usually you call these commands in your configure or build tools (e.g. in Makefile or in configure). Even if you use Code::Blocks you can call pkg-config by surrounding it with backticks.
