<aside>
Why could I set garbage in the cache
file as above with the result that that garbage was read
and ignored with no error message?  Isn't that a CMake bug?

Your suggested change above does work, but the default PLplot
configuration only enables part of the potential configure, build, and install
tests.  Therefore, to remove that limitation on this test, I would like to set the
following CMake options in the PLplot configure step:

-DBUILD_TEST:BOOL=ON -DBUILD_DOC=ON -DBUILD_DOX_DOC=ON

(to build additional PLplot examples in the build tree, to build the
DocBook documentation, and to build the Doxygen documentation.)

I tried

set(dashboard_cache "
...
CMake_TEST_CONTRACT_PLplot_CMAKE_ARGS:STRING=-DBUILD_TEST=ON -DBUILD_DOC=ON -DBUILD_DOX_DOC=ON
...
)

and that partially works:  The relevant PLplot CMakeCache.txt file
includes the line

BUILD_TEST=ON -DBUILD_DOC=ON -DBUILD_DOX_DOC=ON

>From the results, the first part of that line is
accepted and the rest ignored (rather than erroring out, see aside
above).  So what syntax do I have to use to set

BUILD_TEST=ON
BUILD_DOC=ON
BUILD_DOX_DOC=ON

on separate lines in the PLplot CMakeCache.txt file?

Finally, how can I change the default tag currently used
("plplot-5.13.0") for checking out PLplot?
