Error While building the Code in Ubuntu Server

Error While Building the code using ninja

I have a linux server (Ubuntu 20.04) , There i created a conda environment and installed all required dependencies provided in build-ubuntu.yaml

Then,All CUDA and all provided libraries are installed in my conda environment !

Issue is : While 'Configure and build' :

I cloned the repo SphereSfM and I proceeded steps mentioned below:

Step - 1:

      mkdir build
      cd build

Step - 2: Configure

cmake .. \
        -GNinja \
        -DTESTS_ENABLED=ON \
        -DCMAKE_CUDA_ARCHITECTURES=50 \
        -DASAN_ENABLED=True

It went sucessfully and output was came finally as : -- Build files have been written to: /home/ubuntu/workdir/colmap_test_build/SphereSfM/build

Step - 3: Build ninja

Main Issue While Executing the ninja (Building the code) =>

Compilation Error: 'hypot' is not a member of 'ceres' in cost_functions.h

While step 3 ninja is executing , I tried many times , It is stopping at middle and rasing many errors ! Could you Please tell me how to move from here ! I think if this step is completed ! Then the work will be more easier to me

I think it is the version problem of Ceres. I have used the Ceres with the version 2.1.0.
