Make error: multiple target patterns. Stop

[ProodjePindakaas]

When trying to build anything, the make procedure will result in the following error similar to #174:
makefile:153: *** multiple target patterns. Stop.

After looking at the respective line in the makefile I found that APP_LIBNNP (and the variables at line 154 and 155) is defined as the string

make[1]: Entering directory '[....]/n2p2/src/application' nnp-convert nnp-cutoff nnp-dist nnp-predict nnp-prune nnp-select nnp-symfunc make[1]: Leaving directroy '[...]/n2p2/src/application'

Running the makefile with supression of other makefile output as make -s results in normal behavior, however this should not be needed for a normal build procedure.

Additional info:
commit: 539576b
make version: GNU Make 4.4.1

This seems to be specific to the make version 4.4. At least on version 4.2 the compilation works normally. Either this needs an update to make it 4.4 compatible or specify compatible make verions
