Changing the values of arguments N and M in Makefile leads to an error when 'make all'

[Freymat]

Hi,
when I change the values of arguments N and M in the Makefile, I get the following error when executing 'make all':

'make: *** No rule to make target 'gen2-print-n7m5.out/alto-union/ft_best.mlmodel', needed by 'all'. Stop.'

I think this is due to the fact that some N and M values are hardcoded in the last line of the Makefile:

all: gen2-print-n7m5.out/alto-union/ft_best.mlmodel

Shouldn't we have the following line instead ?

'all: gen2-print-n$(N)m$(M).out/alto-union/ft_best.mlmodel'
