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

This warning is for project developers.  Use -Wno-dev to suppress it.

CMake Error at fc_base/gflags-src/CMakeLists.txt:73 (cmake_minimum_required):
  Compatibility with CMake < 3.5 has been removed from CMake.

  Update the VERSION argument <min> value.  Or, use the <min>...<max> syntax
  to tell CMake that the project requires at least <min> but has been updated
  to work with policies introduced by <max> or earlier.

  Or, add -DCMAKE_POLICY_VERSION_MINIMUM=3.5 to try configuring anyway.


-- Configuring incomplete, errors occurred!

在构建 wenet runtime 时报错，如上。

构建命令为：

shell 复制代码

mkdir build && cd build && cmake .. && cmake --build .

构建命令指定版本即可解决：

shell 复制代码

cmake -version
# cmake version 4.1.2

shell 复制代码

mkdir build && cd build && cmake -DCMAKE_POLICY_VERSION_MINIMUM=4.1.2 .. && cmake --build .

需要将原本的 build 目录删了

shell 复制代码
