I want to compile my project with autoconf/automake. There are 2 conditions defined in my configure.ac

AM_CONDITIONAL(HAVE_CLIENT, test $enable-client -eq 1)
AM_CONDITIONAL(HAVE_SERVER, test $enable-server -eq 1)

I want to separate _LIBS from these 2 conditions in Makefile.am

if HAVE_CLIENT

libtest_LIBS = \

    $(top_builddir)/libclient.la

else if HAVE_SERVER

libtest_LIBS = \

    $(top_builddir)/libserver.la

else

libtest_LIBS = 

endif

but else if HAVE_SERVER does NOT work.

How to write 'else if' in makefile.am?

ptomato's code can also be written in a cleaner manner like:

ifeq ($(TARGET_CPU),x86)
  TARGET_CPU_IS_X86 := 1
else ifeq ($(TARGET_CPU),x86_64)
  TARGET_CPU_IS_X86 := 1
else
  TARGET_CPU_IS_X86 := 0
endif

This doesn't answer OP's question but as it's the top result on google, I'm adding it here in case it's useful to anyone else.
