Hi @kateinoigakukun thanks for the patch! We recently upgraded our ICU to 74 and I'll reapply your patch on top of 74 |
The original patch is still under review in the upstream ICU project, but it is needed to unblock the swift-foundation build on WebAssembly. See unicode-org/icu#3067
`U_TIMEZONE` must not be defined and dynamic loading features must be disabled for WASI target.

The original patch is still under review in the upstream ICU project, but it is needed to unblock the swift-foundation build on WebAssembly.
And also adjust CMakeLists.txt and Package.swift to disable timezone and dynamic loading features.
