Yes, Michele mentions it correctly. In our common CDBS rules debian-tde.mk
you can see that in the case of the existence of ninja binary, MAKE and
Ninja generator in DEB_CMAKE_NORMAL_ARGS is set. These values need to be
set together.
When we prepared it, we did not think about a variable, using which it
would be possible to disable the use of Ninja, even if it is present. As
the easiest way is before building to edit the line in debian-tde-mk:
ifneq "$(wildcard /usr/bin/ninja)" ""
When you change the name of the binary, for example to "/usr/bin/ninja-",
the binary will not be found and Ninja will not be used.
BTW, what do you observe the problem using Ninja build in connection with
the debuging?
Thank you for explanations - the problem is it tires to build everything until the end and it does not stop after failure.
I guess it is not a big problem - but need to get familiar or be able to switch it off when needed.
