Hi,

Thank you very much for your answers !
Here is what I did following your advice :

- setting C=mpiicc and CXX=mpiicpc : yes, this worked and removed the errors like "Could NOT find MPI_C (missing:  MPI_C_LIBRARIES)"
- I changed somes values in CMakeCache.txt                          
- I still have the error : CMake Error: Could not open file for write in copy operation /CMakeSystem.cmake.tmp
                           CMake Error: : System Error: Permission denied

                           I checked that I was running cmake in a directory like $HOME/build with full write permissions.
                           Moreover, this error does not show when I try to install ALPS 2.2.0b3 instead.

Do you have any idea ?
Thanks you.
