Is there any documentation somewhere on how the percentage reporting
is implemented ? If not it would really be helpful atleast to get a
hint on which source files to look at. :)
No, not really, it uses a directory to communicate, and cmake -E
cmake_progress_start. If you grep for progress in the source tree
and
look at the Makefiles you can get the idea. It is going to be very
hard to make it work with more than one make in a tree.
If the directory used for communication had a pid as part of its name,
wouldn't that solve it? Or is it more complicated than that? (I'm just
curious.)
Lets say with process 1000 is building target A. Process 2000 is
building target B at the same time. What happens if both depended on
target C (e.g. a library) and tried to build it at the same time
without knowing that there is another process trying to do the very
same thing. This might lead to very buggy builds...
I don't think this is anything CMake could ever possibly handle, as it
also very strongly depends on the native build system (Make, VS,
Xcode,...)
