Import Third-Party CMake Library Example

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

Example Flow

tinyxml2 is a small C++ XML parser.

It is imported, without modification, into the tinyxml2 component. Please refer to the component CMakeLists.txt file for the description of the process: components/tinyxml2/CMakeLists.txt.

To demonstrate the library being used, a sample XML is embedded into the project. This sample XML is then read and parsed using tinyxml2. Please refer to the main component for details.

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"?>
