Hi! I have a project, where for some targets I have a POST_BUILD rule, which 
adds some data about this target into a "central file". If I build a project 
with several threads sometimes I get errors, when both threads try to write 
into this "central file" at the same time.

So I was wondering, if there is some way of doing an exclusive 
lock/mutex/semaphore with CMake scripts?

Maybe you have some other ideas how to correctly write into one file from 
different threads?

Thanks! Denis
