Hello CMake Developers!
Looks like I found interesting bug in CMake:
- ADD_CUSTOM_TARGET() always creates Makefile rule for ADD_CUSTOM_COMMAND().
- As result build simetimes failed if specified -jN for make.
FWIW this is documented behavior (so not exactly a bug):
https://cmake.org/cmake/help/latest/command/add_custom_command.html
"Do not list the output in more than one independent target that may
build in parallel or the two instances of the rule may conflict[...]".
