Check config/examples/arch-ci-mswin-opt-impi.py for an example on specifying IMPI [and MKL - instead of fblaslapack]. And if you don't need MPI - you can use --with-mpi=0

If you are not using PETSc from fortran - you don't need ifort. You can use --with-fc=0 [with MKL or --download-f2cblaslapack]

If you are still encountering errors - send us configure.log for the failed build.

Something a bit suspectable is that I open Cygwin with dos. (actually the Intel Compiler 19.1 Update 3 Intel 64 Visual Studio 2019, x86 environment for the test of ifort ia-32 ,in particularlly)
