Include custom libraries in the VSCode project

Hello, I am using the Arduino extension for months now with no issues.

The new scenario I have is I need to include custom libraries (not from the Arduino library manager). My project structure, which usually works if I rely on the library manager,

The problem, as you may notice, is that I need to include custom libraries found in my include folder. The intellisense works and detects the members and methods. However, when compiling , I get the error

undefined reference to `SDCardMultiSector::SDCardMultiSector(Stream&, char const*, gpio_num_t, gpio_num_t, gpio_num_t, gpio_num_t, gpio_num_t, gpio_num_t)

The function is detected by the Intellisense and included the libraries as it I guess in a correct way.

{

  // this writes a complete sector so we should return sector size on success
  if (card->writeSectors(buffer, lba, bufsize / card->getSectorSize()))
  {
    return bufsize;
  }
  return bufsize;
  // return -1;
}

{

  {
    return bufsize;
  }
  return -1;
}

static bool onStartStop(uint8_t power_condition, bool start, bool load_eject)
{
  //Serial.printf("StartStop: %d %d %d\n", power_condition, start, load_eject);
  if (load_eject)
  {
#ifndef SD_CARD_SPEED_TEST
    msc.end();
#endif
  }
  return true;
}

bool isBootButtonClicked()
{
  return digitalRead(BOOT_BUTTON) == LOW;
}

void setup()
{
  // pinMode(GPIO_NUM_2, OUTPUT);
  card = new SDCardMultiSector(Serial, "/sd", GPIO_NUM_14, GPIO_NUM_15, GPIO_NUM_2, GPIO_NUM_4, GPIO_NUM_12, GPIO_NUM_13);
  msc.vendorID("ESP32");
  msc.productID("USB_MSC");
  msc.productRevision("1.0");
  msc.onRead(onRead);
  msc.onWrite(onWrite);
  msc.onStartStop(onStartStop);
  msc.mediaPresent(true);

  msc.begin(card->getSectorCount(), card->getSectorSize());
  Serial.begin(115200);
  USB.begin();
}

void loop()
{
  // put your main code here, to run repeatedly:
  delay(200);
  // if (isBootButtonClicked())
  // {
  //     if (MySD.cardType() == CARD_NONE)
  //     {
  //         log("No SD card");
  //     }
  // }
}

I tried to include the folder in c_cpp_properties.json but the file is generated, and therefore it is automatically deleted.

I believe this is a common issue and there is a standard solution for it.
