Include Path is not recognized in vscode - c++

Question

I've been reading at almost every question related to include paths in vscode but I just can't solve my issue.
My project folder's custom libraries is in the following path
"/home/gdl/DSS2-DEV/infra"
The infra folder is structured as such:
>Infra
>Include
... some header files
>lib1
>Include
... header files
>src
... cpp files
>lib2
>Include
... header files
>src
... cpp files
So, in order to use any of these libraries, I set up the vscode environment
launch.json
{
"version": "0.2.0",
"configurations": [
{
"name": "g++ - Build and debug active file",
"type": "cppdbg",
"request": "launch",
"program": "${fileDirname}/${fileBasenameNoExtension}",
"args": [],
"stopAtEntry": false,
"cwd": "${workspaceFolder}",
"environment": [ {"name": "LD_LIBRARY_PATH", "value": "/usr/local/lib:$LD_LIBRARY_PATH" }],
"externalConsole": false,
"MIMode": "gdb",
"setupCommands": [
{
"description": "Enable pretty-printing for gdb",
"text": "-enable-pretty-printing",
"ignoreFailures": true
}
],
"preLaunchTask": "C/C++: g++ build active file",
"miDebuggerPath": "/usr/bin/gdb"
}
]
}
tasks.json
{
"version": "2.0.0",
"tasks": [
{
"type": "shell",
"label": "C/C++: g++ build active file",
"command": "/usr/bin/g++",
"args": [
"-g",
"${file}",
"-o",
"${fileDirname}/${fileBasenameNoExtension}",
"-I",
"/home/gdl/DSS2-DEV/infra"
],
"options": {
"cwd": "${workspaceFolder}"
},
"problemMatcher": [
"$gcc"
],
"group": "build"
}
]
}
c_cpp_properties.json
{
"configurations": [
{
"name": "Linux",
"includePath": [
"${workspaceFolder}/**",
"/home/gdl/DSS2-DEV/infra"
],
"defines": [],
"compilerPath": "/usr/bin/gcc",
"cStandard": "c11",
"cppStandard": "c++14",
"intelliSenseMode": "clang-x64"
}
],
"version": 4
}
and yet, not a single library can be included:
cpp file
#include <cstdio>
#include <libadm.h>
int main()
{
return 0;
}
Executing task: /usr/bin/g++ -g /home/gdl/DSS2-DEV/infra/parser.cpp -o /home/gdl/DSS2-DEV/infra/parser -I /home/gdl/DSS2-DEV/infra <
/home/gdl/DSS2-DEV/infra/parser.cpp:2:20: fatal error: libadm.h: No such file or directory
#include <libadm.h>
I tried using slashes but it doesn't change a thing. What drives me crazy is that if I CTRL-click the library it actually shows me the header file of that library, meaning that vscode is correctly linking files togheter.
I also tried using quotes instead of brackets for the include but nothing works
