long filename

[hsdk123]

I'm using

CPMAddPackage(json
  GIT_REPOSITORY https://github.com/ArthurSonzogni/nlohmann_json_cmake_fetchcontent.git
  GIT_TAG v3.9.1
  SYSTEM
)

and get the following error:

-- CPM: Adding package nlohmann_json_cmake_fetchcontent@3.9.1 (v3.9.1)
ninja: error: Stat(C:/Users/daego/Desktop/Projects/Light.vn-core/core/out/build/emscripten/_deps/nlohmann_json_cmake_fetchcontent-subbuild/nlohmann_json_cmake_fetchcontent-populate-prefix/src/nlohmann_json_cmake_fetchcontent-populate-stamp/nlohmann_json_cmake_fetchcontent-populate-done): Filename longer than 260 characters

Any advice would be grateful
