Dave is a software engineer who is currently working on a project called "Octocad." As part of his work, he needs to configure some dependencies in order to compile and run his project successfully. He is using the GLFW library for windowing, and the GLEW library for OpenGL extension loading. In addition, Dave wants to ensure that the necessary library files are linked correctly based on the build configuration (debug or release). Finally, he wants to define a constant variable for the name of his project.

Dave has provided the following code snippet:

```cpp
#pragma comment(lib, "lib/glfw3dll.lib")

#ifndef _DEBUG
#pragma comment(lib, "lib/glew32.lib")
#else
#pragma comment(lib, "lib/glew32d.lib")
#endif

const char* Octocad::NAME = "Octocad v1.0";
```

Your task is to explain the purpose and significance of each line in the code snippet, and provide the correct configuration for Dave's dependencies in different build scenarios.

Write a function `configureDependencies` that takes a boolean parameter `isDebug`, representing the build configuration, and returns a string containing the correct dependency configurations for the given scenario. The string should be in the format `<glfw_config>, <glew_config>` where `<glfw_config>` represents the link configuration for the GLFW library, and `<glew_config>` represents the link configuration for the GLEW library.

Assume the following:
- The `isDebug` parameter can only be true or false.
- The options for `<glfw_config>` are: "glfw3dll" for debug mode, and "glfw3" for release mode.
- The options for `<glew_config>` are: "glew32d" for debug mode, and "glew32" for release mode.

Example:
```cpp
cout << configureDependencies(true);
```
Output:
```
glfw3dll, glew32d
```

Sure, I can help with that. Here's an explanation of each line in the code snippet and how to configure the dependencies based on the build configuration:

1. `#pragma comment(lib, "lib/glfw3dll.lib")`: This instructs the compiler to include the link path (in this case, it points to the directory with the library file(s)) for the `glfw3dll` library in the debug build configuration. In the release configuration, it will look for `glfw3.lib`.

2. `#pragma comment(lib, "lib/glew32d.lib")`: Similar to the above line, but for the `glew32d` library in debug (`_DEBUG`) build configuration. For the release configuration, it will look for `glew32.lib`.

3. `#ifndef _DEBUG`: This is a conditional compilation directive that checks whether the preprocessor constant `_DEBUG` is defined or not. Since it's not defined in the release configuration, it's skipped.

4. `#pragma comment(lib, "lib/glew32.lib")`: This is executed in the release configuration.

5. `#else`: This is executed when `_DEBUG` is defined (in the debug configuration).

6. `#pragma comment(lib, "lib/glew32d.lib")`: This is executed only when `_DEBUG` is defined.

7. `const char* Octocad::NAME = "Octocad v1.0";`: This defines a constant character pointer named `NAME` within the `Octocad` namespace. Its value is a literal string `"Octocad v1.0"`.

As for configuring the dependencies based on the build configuration, you can create a function `configureDependencies` that takes a boolean parameter `isDebug` and returns a string containing the appropriate link configurations. Here's a simple implementation:

```cpp
#include <sstream>

std::string configureDependencies(bool isDebug) {
    std::ostringstream os;

    // Include library directories
    os << "-L" << (!isDebug) ? "lib" : "lib/debug" << std::endl;

    // Link relevant libraries
    if (isDebug) {
        os << "-lglfw3dll -lGLEW32D" << std::endl;
    } else {
        os << "-lglfw3 -lGLEW32" << std::endl;
    }

    return os.str();
}
```

This function returns a string containing the library directory path (if required for your compiler), followed by the linker flags (`-l<library_name>`) for the `glfw` and `glew` libraries based on the build configuration. You can then modify your `main` function, or wherever you're invoking the function, to pass a value of `true` or `false` for `isDebug`. For example, `std::cout << configureDependencies(true) << std::endl;` would print the linker flags for the debug configuration.

The given code snippet is written in C++ and is used to configure dependencies for Dave's "Octocad" project. Here's an explanation of each line:

1. `#pragma comment(lib, "lib/glfw3dll.lib")`: This line is a Microsoft-specific preprocessor directive that links the GLFW library (dynamic link library) for windowing. The "glfw3dll.lib" is used for both debug and release configurations in this case.

2. `#ifndef _DEBUG`: This line checks if the `_DEBUG` macro is not defined. If it is not defined, it means the project is in release mode.

3. `#pragma comment(lib, "lib/glew32.lib")`: Inside the `#ifndef _DEBUG` block, this line links the GLEW library (static library) for OpenGL extension loading in release mode.

4. `#else`: This line introduces an alternative block of code to be executed if the `_DEBUG` macro is defined, meaning the project is in debug mode.

5. `#pragma comment(lib, "lib/glew32d.lib")`: Inside the `#else` block, this line links the GLEW library (static library, debug version) for OpenGL extension loading in debug mode.

6. `const char* Octocad::NAME = "Octocad v1.0";`: This line defines a constant character pointer as a member of the `Octocad` namespace, which stores the name of the project.

Based on your task, here's the implementation of the `configureDependencies` function:

```cpp
#include <string>

std::string configureDependencies(bool isDebug) {
    std::string glfw_config = isDebug ? "glfw3dll" : "glfw3";
    std::string glew_config = isDebug ? "glew32d" : "glew32";

    return glfw_config + ", " + glew_config;
}
```

This function using the ternary operator `? :` to choose the correct library configuration based on the value of the `isDebug` parameter. If `isDebug` is true, it returns "glfw3dll, glew32d" and if `isDebug` is false, it returns "glfw3, glew32".
