Currently, several example dependencies rely on the fact that all registered components are added to the build, along with components specified in common requirements. This results in longer build times because even unused components must be built. Switch all examples to use idf_minimal_build to compile only the components actually required by the example.

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"?>
