+commit 6b215267e7baeae83906bec8dab72a549aeda6c8
+Author: Alan W. Irwin <airwin@users.sourceforge.net>
+Date:   Mon Sep 23 17:39:31 2019 -0700
+
+    Build system: Fix ocaml examples core build for -DUSE_RPATH=OFF case
+    
+    Thanks to Orion Poplawski for reporting this issue which is that the
+    *core build_tree* rpath manipulations for the ocaml examples were
+    being (incorrectly) skipped for the -DUSE_RPATH=OFF case.  The fix for
+    this issue required non-trivial CMake logic changes so was extensively
+    tested (see below).
+    
+    Tested by: Alan W. Irwin <airwin@users.sourceforge.net> on Linux
+    (Debian Buster = Stable) with the following steps:
+    
+    # Choose these prefixes to assure that the source, build, and install
+    # trees have blanks in their pathnames (to test those cases during
+    # this comprehensive test)
+    COMPREHENSIVE_TEST_PREFIX="/home/software/plplot/HEAD/comprehensive_test_disposeable blank"
+    SOURCE_PREFIX="/home/software/plplot/HEAD/plplot blank .git"
+    
+    # Set CMAKE_PREFIX_PATH to access local versions of lua and libLASi to
+    # avoid important bugs in the Debian Testing versions of those
+    # packages.  Also access a local version of libqhull to test that
+    # additional rpath possibility.
+    
+    # Put a local build of CMake-3.15.20190829-g3ec986c first on the PATH to thoroughly
+    # test our build system for a locally built CMake version that includes an
+    # essential fix so that D language support works properly for the ldc2 and dmd compilers.
+    
+    # For this particular test use the gdc D compiler if D enabled (which it was not, see below).
+    
+    # Use the -DUSE_INCRTCL_VERSION_4=ON option to help CMake find Tcl/Tk
+    # components. (This step will not be necessary as soon as the PLplot
+    # build system is modified to make Tcl/Tk/Itcl/Itk/Iwidgets finding
+    # more robust.)
+    
+    # Use -DSWIG_EXECUTABLE=/home/software/swig/install/bin/swig to test
+    # swig-4.0.0 that I built for myself.
+    
+    # To save time, constrain the test to just the ocaml binding and svg device.
+    
+    # To save a lot of babysitting of this test, constrain the test by dropping
+    # the interactive component.
+    
+    time (nice -19 env CMAKE_PREFIX_PATH=/home/software/lua/install-5.3.5:/home/software/lasi_svn/install:/home/software/qhull/install PATH=/home/software/cmake/install-3ec986ce8e/bin:"$PATH" DC=gdc "$SOURCE_PREFIX"/scripts/comprehensive_test.sh --prefix "$COMPREHENSIVE_TEST_PREFIX" --cmake_added_options "-DUSE_INCRTCL_VERSION_4=ON -DSWIG_EXECUTABLE=/home/software/swig/install/bin/swig -DDEFAULT_NO_BINDINGS=ON -DENABLE_ocaml=ON -DDEFAULT_NO_DEVICES=ON -DPLD_svg=ON " --build_command "make -j18" --ctest_command "ctest -j18" --do_test_interactive no)

+    
+    The above test was repeated with the following changes:
+    
+    # Specify LD_LIBRARY_PATH to workaround the lack of special rpath
+    # support for external local versions of software
+    
+    # Use the -DUSE_RPATH=OFF cmake option to drop all install-tree
+    # rpath support (and to ignore any special rpath support for
+    # external local versions of software).
+    
+    # Further constrain the test to be performed just for the core build tree
+    # since -DUSE_RPATH=OFF will obviously give bad results for the install
+    # tree for this non-standard installation location.

+    user    1m42.156s
+    sys     0m26.478s
+    
+    Both these comprehensive tests (one which tests that the default
+    -DUSE_RPATH=ON still works for the ocaml case and one similar to
+    Orion's test case which tests that -DUSER_RPATH=OFF works for the
+    ocaml case in the core build tree) ran without issues (e.g., there
+    were no hangs or other obvious errors) and was followed up by the
+    evaluation procedure documented in doc/wiki_source/Testing_PLplot.
+    Those evaluations showed no configure, build, or obvious run-time
+    errors (i.e., no non-zero return codes for any of the steps in these
+    comprehensive tests), and the difference test results (done with the
+    default svg device) were perfect as well.
