I want to cross compile lapack for armv8 CPU. I have define the fortran complier (aarch64-kedacom-linux-gnu-gfortran) but it still check complier by itself: (base) [root@localhost build]# cmake -DCMAKE_C_COMPLIER=aarch64-kedacom-linux-gnu-gcc -DCMAKE_CXX_COMPLIER=aarch64-kedacom-linux-gnu-g++ -DCMAKE_FORTRAN_COMPLIER=aarch64-kedacom-linux-gnu-gfortran...

When solving the band equations, when the order of the coefficient matrix is 6000,, M=N=6000,KL = 3000, Ku = 3000, nrhs = 3000, the equations program runs for several hours without results? I don't know why?thank you.
