CMake中FindMatlab无法定位指定Matlab版本问题求助

环境信息 #

• 操作系统：Windows 10
• CMake版本：3.26.4
• 已安装Matlab版本：8.2(R2013b)、9.3(R2017b)、9.12(R2022a)、9.13(R2022b)

CMakeLists.txt配置 #

cmake_minimum_required(VERSION 3.26)

project(MatlabMex)

set(MATLAB_FIND_DEBUG ON)

find_package(Matlab 9.3 EXACT REQUIRED)
matlab_extract_all_installed_versions_from_registry(TRUE matlab_versions)
matlab_get_all_valid_matlab_roots_from_registry("${matlab_versions}" matlab_roots)

message("${matlab_roots}")

IF(MATLAB_FOUND)
    matlab_get_release_name_from_version(${Matlab_VERSION_STRING} Matlab_release)
    message(STATUS "Matlab found: ${Matlab_release}")
ELSE(MATLAB_FOUND)
    message("Matlab not found")
ENDIF(MATLAB_FOUND)

问题现象 #

1. 指定Exact版本时的错误
   使用find_package(Matlab 9.3 EXACT REQUIRED)时，FindMatlab调试输出仅识别到9.13版本：

   -- [MATLAB] Matlab root folders are UNKNOWN;9.13;C:/Program Files/MATLAB/R2022b
   -- [MATLAB] Current version is 9.13 located C:/Program Files/MATLAB/R2022b
   -- [MATLAB] [DEBUG]_matlab_lib_prefix_for_search = lib | _matlab_lib_dir_for_search = C:/Program Files/MATLAB/R2022b/extern/lib/win64/mingw64
   

   同时CMake报错无法找到指定的9.3版本：

   Could NOT find Matlab: Found unsuitable version "9.13", but required is
     exact version "9.3" (found C:/Program Files/MATLAB/R2022b/extern/include, )
   

2. 去掉Exact参数后的情况
   移除EXACT参数后，CMake自动选中9.13版本，但通过注册表宏能正确获取所有已安装版本的路径：

   MATLAB;9.13;C:/Program Files/MATLAB/R2022b;MATLAB;9.12;C:/Program Files/MATLAB/R2022a;MATLAB;9.3;C:/Program Files/MATLAB/R2017b;MATLAB;8.2;C:/Program Files/MATLAB/R2013b
   

核心疑问 #

明明注册表中可以查到9.3版本的路径，为何FindMatlab无法直接定位并选中这个指定版本？已查阅过两个已解决的相关CMake Issue，暂倾向于自身配置问题，但找不到根源。
