Use Catch2 for testing proper installation and linking of C++ libraries installed through task

[coderabbitai]

Background

The current approach for testing C++ libraries installed through task (e.g., Boost in PR #42) uses custom C++ programs with manual validation logic and error handling.

For example, in taskfiles/boost/test_boost.cpp, the current implementation:

• Uses a custom main function with manual command-line argument parsing
• Implements individual test functions that return boolean success/failure
• Manually tracks and reports different error codes for various test failures

Proposal

Replace the current custom testing approach with Catch2, a modern C++ test framework that would provide:

• Simpler test declarations with REQUIRE/CHECK macros
• Automatic test registration and discovery
• Better test output with clear failure messages
• Test sections and fixtures for better organization
• Built-in command-line parser with test filtering options
• Seamless integration with CI systems and test report generation
• Reduced boilerplate code

Implementation Steps

1. Add a task to download and install Catch2 (similar to how Boost is installed)
2. Update the test C++ programs to use Catch2's test macros and framework
3. Modify the task running the tests to capture and report Catch2 test results
4. Consider adding this as a standard approach for all C++ library testing tasks

This would standardize testing across all C++ libraries and make it easier to add new tests in the future.
