Fetching polyscope brings in 325MB

[alecjacobson]

I'm using

FetchContent_Declare(
   polyscope
   GIT_REPOSITORY https://github.com/nmwsharp/polyscope.git
   GIT_TAG        v2.6.1
   # shallow
   GIT_SHALLOW    TRUE
)

But GIT_SHALLOW doesn't do much here because of all the submodules (257MB).

Claude recommended:

FetchContent_Declare(
   polyscope
   GIT_REPOSITORY https://github.com/nmwsharp/polyscope.git
   GIT_TAG        v2.6.1
   GIT_SHALLOW    TRUE
   GIT_SUBMODULES ""
)

FetchContent_GetProperties(polyscope)
if(NOT polyscope_POPULATED)
  FetchContent_Populate(polyscope)
  execute_process(
    COMMAND git submodule update --init --recursive --depth 1
    WORKING_DIRECTORY ${polyscope_SOURCE_DIR}
    COMMAND_ERROR_IS_FATAL ANY
  )
  add_subdirectory(${polyscope_SOURCE_DIR} ${polyscope_BINARY_DIR})
endif()

Which brings the total down to 81MB and hopefully isn't missing anything.
