Migrate to conanfile.py and Enhance Build Configuration

[hankhsu1996]

Overview

This PR introduces key improvements to the project's build configuration and CI pipeline.

Added

• conanfile.py:

  • Migrated from conanfile.txt to conanfile.py for enhanced control over the build process.
  • Included ninja and ccache under tool_requires for optimized build performance.
  • Added Catch2 under test_requires to clearly distinguish test dependencies.

• CMake Configuration:

  • Configured ccache as the compiler launcher by setting:
    • CMAKE_C_COMPILER_LAUNCHER = ccache
    • CMAKE_CXX_COMPILER_LAUNCHER = ccache
  • Set Ninja as the default build generator (tc.generator = "Ninja").
  • Updated the generate() method to create a ConanPresets.json, enabling extension with a custom CMakePresets.json.

• CI Integration:

  • Implemented ccache caching in the GitHub Actions workflow to speed up subsequent builds.

Changed

• CI Workflow (ci.yml):

  • Updated to use the new release and debug CMake presets instead of the previous default preset.

• Documentation:

  • Updated the README to reflect the new build and test instructions, emphasizing the use of ccache and ninja for faster builds.

Benefits

• Faster Builds: Leveraging ccache and ninja significantly reduces build times, especially in CI environments.
• Improved Control: The migration to conanfile.py offers greater flexibility in managing dependencies and build configurations.
• Streamlined CI: The updated presets simplify the CI process, making it more maintainable and efficient.
