1CMake Warning (dev) at /root/miniconda3/share/cmake-4.1/Modules/FetchContent.cmake:1373 (message): 2 The DOWNLOAD_EXTRACT_TIMESTAMP option was not given and policy CMP0135 is 3 not set. The policy's OLD behavior will be used. When using a URL 4 download, the timestamps of extracted files should preferably be that of 5 the time of extraction, otherwise code that depends on the extracted 6 contents might not be rebuilt if the URL changes. The OLD behavior 7 preserves the timestamps from the archive instead, but this is usually not 8 what you want. Update your project to the NEW behavior or specify the 9 DOWNLOAD_EXTRACT_TIMESTAMP option with a value of true to avoid this 10 robustness issue. 11Call Stack (most recent call first): 12 cmake/gflags.cmake:1 (FetchContent_Declare) 13 cmake/openfst.cmake:2 (include) 14 CMakeLists.txt:44 (include) 15This warning is for project developers.

在构建 wenet runtime 时报错，如上。
构建命令为：
1mkdir build && cd build && cmake .. && cmake --build . 2
构建命令指定版本即可解决：
1cmake -version 2# cmake version 4.1.2 3
1mkdir build && cd build && cmake -DCMAKE_POLICY_VERSION_MINIMUM=4.1.2 .. && cmake --build . 2
需要将原本的 build 目录删了
