This fixes the build error caused by the presence of a whitespace character in the path used to build this project on https://build.kde.org/. The source of the whitespace is the environment variable JOB_BASE_NAME (set to 'kf5-qt5 SUSEQt5.12'). However, it would be a good idea to fix this in the cmake code, too.
The space is principally in the name to expose failures such as this one (because spaces in paths created by users are common, and are almost guaranteed to be included in the installation path on Windows as well).
Thanks for looking into this breakage!
This change looks fine to me, but i'll leave it to someone more experienced with CMake to review this
I wasn't aware of another revision being under review to fix the same issue, sorry.
D23219 is the simpler fix, using only the file name to create a target name. Unless this cmake module could be reused in other projects, that fix is sufficient to address this broken build issue.
If the cmake module is going to be reused, however, D23219 needs to be hardened further to address two potential breakages: if the file name has spaces in it, or if there are multiple files in the same repository that share the same name. We could guard against the first by using a STRING(REPLACE ...) fix like in this revision, and against the latter by checking with IF (TARGET ...) and adding an incrementing numeric suffix to the target name, as needed. The current patch can be reused in other projects as is.
If reuse is not a concern, I think I'd go with the simpler fix (D23219), to be honest.
