FetchContent not respecting DOWNLOAD_NO_EXTRACT
Cmake 3.11.4
The FetchContent module does not seem to respect the ExternalProject_Add download option DOWNLOAD_NO_EXTRACT, despite claiming to understand all download and patch options.
For whatever reason whatever URL is passed ends up being downloaded as archive.tar in \tmp\json-populate-prefix\src, which is obviously invalid. The file is, besides it's name and extension, is otherwise downloaded correctly.
This leads to the following errors
CUSTOMBUILD : CMake error : Problem with archive_read_open_file(): Unrecognized archive format
CUSTOMBUILD : CMake error : Problem extracting tar: archive.tar
