On Windows 10 Home, version 1909
Compiler VS2019 (irrelevant)

To Reproduce
Steps to reproduce the behavior:
./vcpkg install freeglut:x64-windows

Observed behaviour
Extracting archive freeglut-3.0.0.tar.gz fails (download succeeds).
Similar to issue #5861, identical to the situation in the comment by GreenEminence.
I found that the problem is due to a symbolic link in the archive. See below for more details.

the extract-err.log shows this:
CMake Error: Problem with archive_write_header(): Can't create '' CMake Error: Current file: freeglut-3.0.0/progs/test-shapes-gles1/android_toolchain.cmake CMake Error: Problem extracting tar: C:/Users/greeneminence/dev/vcpkg/downloads/freeglut-3.0.0.tar.gz

Additional context
The file freeglut-3.0.0/progs/test-shapes-gles1/android_toolchain.cmake in the archive is a symbolic link.
7zip has problems extracting this file. When I run 7zip (outside vcpkg) on the downloaded freeglut-3.0.0.tar,gz file, it gives this error message:
"Can not create symbolic link: one of the required permissions is not granted to the client"

When I do 7zip "run as administrator", it can unpack the archive. This is in line with this bug report on 7zip:
https://sourceforge.net/p/sevenzip/bugs/1599/
The maintainer of 7zip seems to treat this as a feature, not a bug.

Although I can extract the archive now, I don't know how to do this in combination with vcpkg.

• Using an administrator to run vcpkg account is not enough (for 7zip)
• If I patch the tar.gz-archive, by replacing the symbolic link by a copy of the file it refers to and put that in the downloads folder, vcpkg rightfully detects a wrong checksum.
• I don't know if I can put the extracted source somewhere in the buildtree, so vcpkg will skip the extraction step. That would be another workaround.
