SDK Compatibility with CMake Version > 4.0

brunod

Hello,

I'm facing some issues compiling the SDK with cmake version > 4.0.

I’ve observed that CMake 4.0 drops support for CMakeLists.txt file with version older than 3.5, which appears to be required by the l8w8jwt library (a dependency of the SDK).

Could you please confirm which SDK version supports CMake version > 4.0?

Thank you,

Thank you for reaching out to us.

I tested it with cmake version 4.0.3 and it can build the latest code on GitHub with the following command.

cmake ../ -DBUILD_UNIT_TESTS=OFF -DBUILD_ETA_EXAMPLES=OFF

However, it needs to set the following environment variable.

export CMAKE_POLICY_VERSION_MINIMUM=3.5

Otherwise, cmake will show the following error.

CMake Error at CMakeLists.txt:2 (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.
