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?
