PokedexSchema.hpp is undefined, multisource example - c++ cpp

I am trying to follow the example to parse a PokemonSchema serialized string.

I am using the instructions in `PokemonSchema.hpp`
```
// To parse this JSON data, first install
//
// json.hpp https://github.com/nlohmann/json
//
// Then include this file, and then do
//
// PokedexSchema.hpp data = nlohmann::json::parse(jsonString);
```
And using this code, I get the error identifier "PokemonSchema" is undefined.

```
#include "stdafx.h"
#include
#include

#include
#include "PokedexSchema C++ (quicktype)/PokedexSchema.hpp"

int main(int argc, char* argv) {
std::string jsonString = "{}";

PokedexSchema.hpp data = nlohmann::json::parse(jsonString);

}

```

So I tried to parse it directly into the object, as would be done in the single source solution:
```
// To parse this JSON data, first install
//
// json.hpp https://github.com/nlohmann/json
//
// Then include this file, and then do
//
// PokedexSchema data = nlohmann::json::parse(jsonString);
```
```
#include "stdafx.h"
#include
#include

#include
#include "PokedexSchema C++ (quicktype)/PokedexSchema.hpp"

int main(int argc, char* argv) {
std::string jsonString = "{}";

quicktype::PokedexSchema data = nlohmann::json::parse(jsonString);

}
```
I receive the following error at compile-time.
`E0312 no suitable user-defined conversion from "nlohmann::basic_json" to "quicktype::PokedexSchema" exists`

So what is the correct way to parse a jsonString into a Multi-source solution custom object in cpp?
