ENH: install helpers to assist when installing into system mpi directories

- the problem noted in issue #1893 is caused by the rpm-mpi-hooks
  (fedora and redhat-8).

  For the additional mpi library qualifier (openmpi-x86_64) to be
  added to the requirements, the mpi-specific libraries (eg,
  libPstream.so) need to be installed in the mpi system directory
  (eg, /usr/lib64/openmpi).

  However, need to then create symlinks to ensure that the libraries
  are correctly found via our LD_LIBRARY_PATH and we don't get dummy
  libraries.

-    dirToString
-
-Description
-    Converts a directory path into a camelCase string.
-    e.g. dir1/dir2/dir3 becomes dir1Dir2Dir3
-
-Usage
-    echo dirName | dirToString
-
-    e.g.
-        using sh
-        baseDirName=$(echo $dir | $bin/dirToString -strip)
-
-        using csh
-        set baseDirName=`echo $dir | $bin/dirToString -strip`

 # Description
-#     General, easy to use make system for multi-platform development
-#     with support for local and network parallel compilation.
+#     General, wrapped make system for multi-platform development.
 #
-#     This updated wmake supports out-of-tree object and dependency files to
-#     avoid the clutter which accumulates in the source-tree with the original
-#     wmake system.  Now when building the OpenFOAM package both the object and
-#     dependency files are now located in a tree with the same structure as the
-#     source tree but in the platforms/$WM_OPTIONS sub-directory of
-#     $WM_PROJECT_DIR.
+#     Intermediate object and dependency files retain the tree structure
+#     of the original source files, with its location depending on the
+#     build context.
 #
-#     When building user libraries and applications which are not located in the
-#     OpenFOAM source-tree the object and dependency files are located in a tree
-#     with the same structure as the source tree but in the Make/$WM_OPTIONS
-#     sub-directory.
+#       1. Building within the OpenFOAM project:
+#          The tree is located under $WM_PROJECT_DIR/build/$WM_OPTIONS/
 #
-#     The disadvantage of the out-of-tree compilation is that the dependency
-#     files are harder to find but are sometimes useful to study which header
-#     files are included.  For those who need access to the dependency files the
-#     new wdep script is provided to locate them.  See the wdep script header or
-#     run:
-#         wdep -h
+#       2. Building applications or libraries outside the OpenFOAM project:
+#          The tree is located under its local Make/$WM_OPTIONS/
+#
+#     The `wdep` script can be used to locate the dependency file
+#     corresponding to a given source file.
+#
+#     When `wmake -all` is used, the following rules are applied:
+#     1. If `Allwmake.override` exists, use it.
+#     2. (OR) If `Allwmake` exists, use it.
+#     3. (OR) descend into each sub-directory and repeat.
