error says : Requried Library BLAS API not found" ..
So, I'm guessing you need to let your program know where BLAS libraries are installed
Could you please set environment variables:
BLAS_LIB_DIR = path to BLAS libraries
LAPACK_LIB_DIR = path to LAPACK libraries
and then rerun cmake-gui again?
FindBLAS.cmake and/or FindLAPACK.cmake are failing to locate your MKL install.
Can you please send me your CMakeLists.txt files? I think we need to specify your environment related information in this file. Which OS (version)are you using?
