I am trying to compile Magma 2.5 on my laptop with NVIDIA GTX 960M, and it always prompts the linkage problem.

I have upgraded cmake version to thew newest available (3.14.3). Below is part of the error output.

Try adding the following files to the libsparse_all target inside CMake.src file:

sparse/blas/magma_dsampleselect_core.cu
sparse/blas/magma_sampleselect.cu
sparse/blas/magma_ssampleselect_core.cu

I have not yet verified this solution due to slow recompilation.
