CMake target names must be distinct from the name of what the target
produces (the executable in this case).  I fixed this issue with revision
8524, and the build works now.

I also made further changes (revision 8526) to allow ctest of ocaml to work.

If in the build tree you now execute

export LD_LIBRARY_PATH=`pwd`/src

(so that libplplotd could be found), then

ctest --verbose -R ocaml

works.

You must hit carriage return to get the ocaml examples to work because they
appear to be stuck in interactive mode.

Orion, the interactivity of this ctest might disrupt your packaging efforts,
but I assume that could be straightforwardly solved by either using the
default disabling of ocaml (which is done because these bindings and
examples are still far from mature) or by finding a ctest -R option that
excludes the ocaml test.

For now, I would like to have the ocaml ctest available so that developers
can easily play with it if they use the combination of cmake options

-DENABLE_ocaml=ON -DBUILD_TEST=ON

Hez, how far are you from getting command-line parsing to work for ocaml?
That would be a huge step forward.
