Hello, I am having problems building and installing the Parallel Graph Library which depends on Boost.MPI, which requires an MPI package. I have the Microsoft MPI runtime and SDK properly installed and a quick "where mpiexec" command in a cmd terminal finds it. Likewise, the compiler (Visual Studio 2022, v143) is easily found in the path. However, b2 can not find the MSMPI. It generates an error that doesn't make sense...it read as follows: *error: Unable to find file or target named error: '/mpi//impi' error: referred to from project at error: ''* WHICH INDICATES THAT IT IS LOOKING FOR THE INTEL MPI!....YET MY USER-CONFIG.JAM FILE IS AS FOLLOWS: using mpi : "C:/Program Files/Microsoft MPI/Bin/mpiexec.exe" : <include>"C:/Program Files (x86)/Microsoft SDKs/MPI/Include" <library-path>"C:/Program Files (x86)/Microsoft SDKs/MPI/Lib/x64" <find-shared-library>msmpi ; Your help will be very much appreciated! Thanks in advance! TI
