vcpkg/ports/mimalloc/usage

mimalloc provides CMake targets:

  find_package(mimalloc CONFIG REQUIRED)
  target_link_libraries(main PRIVATE $<IF:$<TARGET_EXISTS:mimalloc-static>,mimalloc-static,mimalloc>)

To ensure the mimalloc-override.dll is loaded at runtime on Windows with
dynamic linkage, it is suggested to insert some call to the mimalloc API
in the main function, eg. `mi_version()`. Cf.
