#2831: ExternalLibraries/MPI creates MPI_INC_DIRS that have double quotes in their value

 Reporter: Roland Haas
   Status: new
Milestone: 
  Version: 
     Type: bug
 Priority: minor
Component: EinsteinToolkit thorn

ExternalLibraries/MPI’s `detect.pl` script creates entries in `make.MPI.defn` like this \(on stampede3\):

```
MPI_DIR      = /opt/intel/oneapi/mpi/2021.11
MPI_INC_DIRS = "/opt/intel/oneapi/mpi/2021.11/include"
MPI_LIB_DIRS = "/opt/intel/oneapi/mpi/2021.11/lib"
MPI_LIBS     = mpicxx mpifort mpi rt pthread dl
```

which is incorrect since make makes the double quotes part of the variables value. This is usually safe when used in the shell since `-L"Foo"` is the same as `-LFoo` but fails with Silo which stores the options in a string \(and does not escape embedded quotes\).

Since make does not handle spaces well anyway `detect.pl` should not output any quotes since the paths will never contain one.
