【问题描述】：

我正在尝试使用 CMake 构建一个 Windows 库：

The following ICU libraries were not found:
  uc (required)
  i18n (required)
  data (required)
CMake Error at C:/Program Files/CMake/share/cmake-3.25/Modules/FindPackageHandleStandardArgs.cmake:230 (message):
  Failed to find all ICU components (missing: ICU_LIBRARY
  _ICU_REQUIRED_LIBS_FOUND) (found version "72.1")
Call Stack (most recent call first):
  C:/Program Files/CMake/share/cmake-3.25/Modules/FindPackageHandleStandardArgs.cmake:600 (_FPHSA_FAILURE_MESSAGE)
  C:/Program Files/CMake/share/cmake-3.25/Modules/FindICU.cmake:333 (FIND_PACKAGE_HANDLE_STANDARD_ARGS)
  cmake/MapnikFindPackage.cmake:20 (find_package)
  CMakeLists.txt:155 (mapnik_find_package)

我从这里下载了版本：https://github.com/unicode-org/icu/releases/download/release-72-1/icu4c-72_1-Win64-MSVC2019.zip

解压到c:\icu。

我如何告诉 CMake 在哪里可以找到 ICU 二进制文件？

经验法则是设置CMAKE_PREFIX_PATH，外部库的安装路径列表以分号分隔：https://cmake.org/cmake/help/latest/variable/CMAKE_PREFIX_PATH.html
