CMake 文件下载获得 35;"SSL connect error"

Question

我试着"为下面的CMakeLists.txt，但得到

状态为35;"SSL连接错误">

—Internet连接失败

但是，我可以成功运行bellow而没有错误

curl https://librealsense.intel.com/Releases/connectivity_check

请帮忙检查问题出在哪里?

下面是CMakeLists.txt

project(test)
cmake_minimum_required(VERSION 3.16)
message(STATUS "Checking internet connection...")
file(DOWNLOAD "https://librealsense.intel.com/Releases/connectivity_check" "${CMAKE_CURRENT_SOURCE_DIR}/connectivity_check" SHOW_PROGRESS TIMEOUT 5 STATUS status)
message("Status is ${status}")
list (FIND status ""No error"" _index)
if (${_index} EQUAL -1)
message(STATUS "Failed to identify Internet connection")
set(INTERNET_CONNECTION OFF)
else()
message(STATUS "Internet connection identified")
set(INTERNET_CONNECTION ON)
endif()
