HI,

Very well, that’s one possible cause out of the way. 
Luckily Pascal found something else, so hopefully that’s solved..

Thanks,
Jaap

Hi, 
 
The module CheckFunctionExists [1] has been around from at least cmake 3.0, so that’s not new. The first question then would be if, besides cmake, the cmake modules are installed as well?
 
 
Thanks,
Jaap

    editcap doc: Fix description of split output file names
    
    The editcap documentation still refers to the pre 1.2.1 behavior
    of determining output file names when splitting based on either
    packet counts or time intervals. (See commit a8eb860103) Update
    it to reflect the current behavior.
