I installed CMake and MinGW.

CMake Error at C:/Program Files (x86)/CMake/share/cmake-3.4/Modules/FindPackageHandleStandardArgs.cmake:148 (message):
  Could NOT find CURL (missing: CURL_LIBRARY CURL_INCLUDE_DIR)
Call Stack (most recent call first):
  C:/Program Files (x86)/CMake/share/cmake-3.4/Modules/FindPackageHandleStandardArgs.cmake:388 (_FPHSA_FAILURE_MESSAGE)
  C:/Program Files (x86)/CMake/share/cmake-3.4/Modules/FindCURL.cmake:61 (FIND_PACKAGE_HANDLE_STANDARD_ARGS)

sudo apt update &&
sudo apt upgrade &&
sudo apt install curl libcurl4-openssl-dev

Just search the internet for curl! It's a library to transfer data with an URL syntax. You can download binaries from it's download page or download the source code and compile it locally. If you use NuGet, you can grab their package instead.

If it is installed, delete your CMakeCache.txt file and re-run CMake. If you don't want to install it, pass -DCURL_LIBRARY=<curl_lib_path> -DCURL_INCLUDE_DIR=<curl_include_path to your CMake call.
