按照ocr-api-20210707\README-CN.md中的说明,用vcpkg(vcpkg安装在D:/github/vcpkg)执行了:
vcpkg install boost openssl-windows cpprestsdk
结果为：
D:\github\vcpkg>vcpkg install boost cpprestsdk openssl-windows
warning: Starting with the September 2023 release, the default triplet for vcpkg libraries will change from x86-windows to the detected host triplet (x64-windows). To resolve this message, add --triplet x86-windows to keep the same behavior.
Computing installation plan...
The following packages are already installed:
boost[core]:x86-windows -> 1.82.0#1
cpprestsdk[brotli,compression,core,default-features]:x86-windows -> 2.10.18#2
openssl-windows[core]:x86-windows -> deprecated
boost:x86-windows is already installed
cpprestsdk:x86-windows is already installed
openssl-windows:x86-windows is already installed
Restored 0 package(s) from C:\Users\Administrator\AppData\Local\vcpkg\archives in 157 us. Use --debug to see more details.

cpprestsdk provides CMake targets:

# this is heuristically generated, and may not be correct
find_package(cpprestsdk CONFIG REQUIRED)
target_link_libraries(main PRIVATE cpprestsdk::cpprest cpprestsdk::cpprestsdk_zlib_internal cpprestsdk::cpprestsdk_brotli_internal)

继续按照EADME-CN.md，并参照vcpkg的说明，使用“VS2015 开发人员命令提示”执行以下命令：
D:\github\alibabacloud-cpp-sdk\ocr-api-20210707>cd cmake_build
D:\github\alibabacloud-cpp-sdk\ocr-api-20210707\cmake_build>cmake .. -G "Visual Studio 14" -DCMAKE_TOOLCHAIN_FILE=D:/github/vcpkg/scripts/buildsystems/vcpkg.cmake

看起来貌似是CMake没有找到CPPREST_LIB（boost库能找到但是有警告），这里有什么解决办法吗？
是否对开发工具版本，或者CMake版本有其他要求？
