In raising this issue, I confirm the following:

I have read and understood the contributors guide.
I have checked that the bug-fix I am reporting can be replicated, or that the feature I am suggesting isn't already present.
I have checked that the issue I'm posting isn't already reported.
I have checked that the issue I'm porting isn't already solved and no duplicates exist in closed issues and in opened issues
I have checked the pull requests tab for existing solutions/implementations to my issue/suggestion.
I have used the latest available version of CCExtractor to verify this issue exists.
I have ticked all the boxes in this section and to prove it I'm deleting the section completely to remove boilerplate text.

Necessary information

Is this a regression (i.e. did it work before)? Yes, assuming it worked before
What platform did you use? Linux
What were the used arguments? This was during compilation

Video links

Additional information

As explained in the compilation docs I ran cmake ../src -DWITH_HARDSUBX=ON followed by make and got the compilation failed with the following error. (There are more logs on top but these seem to be the relevant ones)

Using the build_hardsubx script gives the same error message.

Sorry for the dupe. Should I close and mark as completed?
