Have you tried running a simple MPI code that you compiled yourself using the same MPI installation?

Dear ALPS users, I am trying to run a spinmc simulation in the parallel mode by using the command mpiexec -np 2 spinmc --mpi parm2a.in.xml --Tmin 5
On executing the command I am getting the following error messages

I have tried running a band structure code in the parallel mode using the mpirun and i am having no problems in running that code. but in the case of ALPS, I am encountering the above problem. I am attaching the cmake txt file for your consideration to make sure that all the fields are correct. I have crosschecked the MPI library path in cmake txt file and i find it to be alright. I am not able to figure out what exactly is causing this problem. I am kindly requesting you to provide me help in solving this issue.
I thank you in advance for your time and consideration.
with best regards Sunil
