Makefile I can't figure out what the error is, do I remove the condition and switch to another one?

Question

linux

I can’t understand what the error is, with tabulation everything is fine, if I remove the condition it goes to the bottom one, I remove the bottom one, it goes even lower, the error starts line number 7 is if ENABLE_MAN
Makefile: 7: *** missing separator. Stop.

ACLOCAL_AMFLAGS = -I build-aux/m4
SUBDIRS = src
if ENABLE_MAN
SUBDIRS += doc/man
endif
.PHONY: deploy FORCE

export PYTHONPATH

if BUILD_BITCOIN_LIBS
pkgconfigdir = $(libdir)/pkgconfig
pkgconfig_DATA = libinvestcoinconsensus.pc
endif

The make language does not have a if .... There are all sorts of others . Automake seems to work ifdef ...
if ...for you, but to get a working Makefile, the original Makefile.am needs to be run through automake, and the resulting Makefile.in needs to be run through configure.
