The typical way to solve that is to assign to a variable, e.g.

ifeq ($(USE_EXTERNAL_LCMS), true)
   # If we're using an external library, we'll just need the wrapper part.
   # By including it explicitely, all other files will be excluded.
   BUILD_LIBLCMS_INCLUDE_FILES := LCMS.c
else
   BUILD_LIBLCMS_INCLUDE_FILES :=
endif

and then using
     INCLUDE_FILES := $(BUILD_LIBLCMS_INCLUDE_FILES), \
inside the build declaration.
