#138 Add initial CMake support

[YarikTH]

CMake is checked to work as a cmake subdirectory and as an installed cmake package.

See usage example at https://github.com/YarikTH/v8pp_cmake_integration_test

Hi,

thank you for the work! I also have an unpublished branch for CMake support, where v8pp/config.hpp is generated from a list of CMakeList.txt options. I will look how to combine it with you approach.

Points to improve:

• Move Config.cmake.in and FindV8.cmake into cmake or support/cmake folder
• Add CMakeLists.txt to plugins and add ctest target equivalent to "./v8pp_test -v --run-tests test/console.js test/file.js"
• See at https://github.com/friendlyanon/cmake-init for more ideas, especially at the usage of CMakePresets.json
  • By the way, they had template for vcpkg support that was requested some time ago Support Vcpkg #128
