IntelliSense can find C++ header files, compiler can not (VSCODE) - c++

Question

I am trying to include the SOCI library in my C++ library. The compilation fails with:
fatal error: soci/soci.h: No such file or directory
3 | #include "soci/soci.h"
I have downloaded and built the library in the path:
/users/niko/.env/libraries
My c_cpp_properties.json looks like:
{
"configurations": [
{
"name": "Linux",
"includePath": [
"${workspaceFolder}/**",
"users/niko/.env/libraries/include/**"
],
"defines": [],
"compilerPath": "/opt/devtoolset//gcc",
"cStandard": "gnu17",
"cppStandard": "c++20",
"intelliSenseMode": "linux-gcc-x64",
"compilerArgs": [
"-Wall",
"-Wextra",
"-Wconversion",
"-Wpedantic",
"-I /users/niko/.env/libraries/include/**"
]
}
],
"version": 4
}
And correspondingly, the tasks.json looks like:
{
"version": "2.0.0",
"tasks": [
{
"type": "cppbuild",
"label": "C/C++: cpp build active file",
"command": "/opt/devtoolset//cpp",
"args": [
"-fdiagnostics-color=always",
"-I",
"users/niko/.env/libraries/include/*",
"-g",
"${file}",
"-o",
"${fileDirname}/${fileBasenameNoExtension}"
],
"options": {
"cwd": "${fileDirname}"
},
"problemMatcher": [
"$gcc"
],
"group": "build",
"detail": "compiler: /opt/devtoolset//cpp"
}
]
}
IntelliSense correctly finds it from this path, but the compilation fails. I have tried various things on SO, but nothing seems to work.
