            Bug ID: 429799
           Summary: kdoctools build if using zsh, antigen and
                    zsh-autosuggestions
           Product: frameworks-kdoctools
           Version: 5.76.0
          Platform: Compiled Sources
                OS: Linux
            Status: REPORTED
          Severity: minor
          Priority: NOR
         Component: general

  Target Milestone: ---

SUMMARY
kdoctools fails to build on systems who use 
(i) zsh, 
(ii) antigen and 
(iii) zsh-autosuggestions
due to a regression in the DocBookXSL finding algorithm used by cmake

Possibly related to #373896

STEPS TO REPRODUCE
1. Install antigen, make sure you have zsh-autosuggestions on PATH
2. run `kdesrc-build kdoctools`
3. Look at cmake.log and build.log

OBSERVED RESULT
The build fails, as it tries to search for the folder manpages in ~/.antigen
which is where its not supposed to look for DocBookXSL. Possibility is that
there is a VERSION file in ~/.antigen/bundles/zsh-users/zsh-autosuggestions/
which makes cmake think that it _is_ the DocBookXSL directory; The build
subsequently fails

EXPECTED RESULT
The build should complete successfully
