VS Code配置Poco库CMakeLists.txt遇兼容及PCRE2查找问题求助

环境信息 #

• Windows 10 + VS Code
• 编译器：g++（来自MSYS2 Mingw64）
• vcpkg安装路径：C:/src/vcpkg
• 已通过vcpkg安装Poco、PCRE2等库

初始CMakeLists.txt配置 #

set(CMAKE_CXX_STANDARD 20)
set(CMAKE_TOOLCHAIN_FILE "C:/src/vcpkg/scripts/buildsystems/vcpkg.cmake"
    CACHE STRING "Vcpkg toolchain file")

# Add the directory where your packages are installed
set(CMAKE_PREFIX_PATH "${CMAKE_PREFIX_PATH};C:/src/vcpkg/installed/x86-windows")

set(CMAKE_FIND_PACKAGE_PREFER_CONFIG TRUE)

# Set the path to the Poco package configuration files
# set(Poco_DIR "C:/src/vcpkg/")

find_package(poco REQUIRED COMPONENTS Foundation JSON) 

阶段1：架构不兼容错误 #

调整配置后出现如下错误：

[cmake] Could not find a configuration file for package "poco" that is compatible
[cmake] with requested version "".
[cmake]
[cmake] The following configuration files were considered but not accepted:
[cmake]
[cmake] C:/src/vcpkg/installed/x86-windows/share/poco/pocoConfig.cmake, version: 1.12.4 (32bit)

尝试设置set(CMAKE_GENERATOR_PLATFORM "x86")无效，随后切换安装x64版本的Poco库。

阶段2：PCRE2库找不到错误 #

切换到x64库后，出现新的CMake错误：

[cmake] -- Found ZLIB: C:/src/vcpkg/installed/x64-windows/lib/zlib.lib (found version "1.2.13") 
[cmake] CMake Error at C:/Program Files/Microsoft Visual Studio/2022/Community/Common7/IDE/CommonExtensions/Microsoft/CMake/CMake/share/cmake-3.24/Modules/FindPackageHandleStandardArgs.cmake:230 (message):

[cmake]   C:/src/vcpkg/installed/x64-windows/share/poco/PocoConfig.cmake:35 (find_package)
[cmake]   CMakeLists.txt:19 (find_package)

已确认PCRE2库存在于C:\src\vcpkg\installed\x64-windows\lib路径下：

-a----        30/05/2023     14:43          20424 pcre2-16.lib
-a----        30/05/2023     14:43          20424 pcre2-32.lib
-a----        30/05/2023     14:42          19974 pcre2-8.lib
-a----        30/05/2023     14:43           2362 pcre2-posix.lib

调整配置（使用Ninja生成器，指定Mingw64编译器）后，错误依旧：
