 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!

Answer 1

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.
