 CMake Error at CMakeLists.txt:186 (message):
  Zstandard: must be static

what's the maining of "Zstandard: must be static" ???

Please tell me how to fix it or how to install SEAL on Windows. Thanks!

Solution

SEAL requires Zstandard to be built statically. You can only use vcpkg to install a static SEAL if you want to have Zstandard support. To do this, specify the triple as follows (for example): .\vcpkg install seal:windows-x64-static.
