error while building wheels for qdldl

[Mahalakshmivignesh]

I am trying to install qdldl==0.1.7.post5 using pip install qdldl==0.1.7.post5 . But it fails in the wheel building step. Below is my error.

My cmake version is 3.26.5-2.el9 . Any suggesions on how to get rid of this error?

That error message is from CMake 4.0, so you aren't actually using the cmake version you say. We have fixed that already in the C code version 0.1.8, but we still need to update the Python wrapper to 0.1.8.

But still my qdldl install fails with the below error.

  CMake Error at qdldl/CMakeLists.txt:2 (cmake_minimum_required):
    Compatibility with CMake < 3.5 has been removed from CMake.

As discussed in osqp/osqp#740 (comment) do we have need to push the cmake_minimum_required version changes to qdldl latest version?

i have created osqp/qdldl-python#60 as i am using python version in my project. It wud be of great help if i get any resolution there. Shall i close this ticket?
