# Import Third-Party CMake Library Example

This example demonstrates how to import third-party CMake libraries.

## Example Flow

[tinyxml2](https://github.com/leethomason/tinyxml2) is a 
a small C++ XML parser. It is imported, without modification, for use in the project's `main` component (see the `main` component's [CMakeLists.txt](main/CMakeLists.txt)). To demonstrate the library being used, a sample XML is embedded into the project.
This sample XML is then read and parsed later on using `tinyxml2`.

### Output

```
I (317) example: Setting up...
I (317) example: Copying sample XML to filesystem...
I (647) example: Reading XML file
I (657) example: Read XML data:
<?xml version="1.0" encoding="UTF-8"?>
<note>
    <to>Tove</to>
    <from>Jani</from>
    <heading>Reminder</heading>
    <body>Don't forget me this weekend!</body>
</note>

I (667) example: Parsed XML data:

To: Tove
From: Jani
Heading: Reminder
Body: Don't forget me this weekend!
I (677) example: Example end
```
