How to use the engine in a personal project

Use the engine as a library (shared or static)

include(FetchContent)
FetchContent_Declare(
    newleaf
    GIT_REPOSITORY https://github.com/kafkaphoenix/newleaf.git
    GIT_TAG        v0.1.0
)

FetchContent_GetProperties(newleaf)
if (NOT newleaf_POPULATED)
  FetchContent_Populate(newleaf)
  set(BUILD_SHARED_LIBS ${BUILD_SHARED_LIBS} CACHE INTERNAL "" FORCE)
  add_subdirectory(${newleaf_SOURCE_DIR} ${newleaf_BINARY_DIR})
endif()
