CMake has both target and file dependencies which are handled automatically and correctly for ordinary targets, but such dependencies can be tricky to implement for custom targets and their associated custom commands (which are often used in our documentation build). Furthermore, finding such dependency problems can be tricky because actual build errors resulting from dependency issues can depend very much on platform, timing (especially from race conditions that sometimes are the result of dependency issues) and what targets are run in what order. So it is good you found and reported the above issue. Further investigation found a file-dependency issue in the custom command associated with the docbook_plplot-symbols_txt target. I have fixed that file-dependency issue as of commit 673c09b, and the result works for the simple test I did. However, please do the exact sequence of commands you did before (to get the timing right just in case the above problem was due to a build-system race condition) to see if the issue you found is now fixed.
