Error in Makefile during a simple check for existing file

within a makefile I need to check if a file exists. Regarding to this answer from holms, I tried it in this way:

all:
    ifeq ("","$(wildcard testFile)")
       echo "File exists"
    else
       echo "File is missing"
    endif

Nevertheless I get this error: 

ifeq ("","")
/bin/sh: 1: Syntax error: word unexpected (expecting ")")
Makefile:3: recipe for target 'all' failed
make: *** [all] Error 2

Where is my mistake and how to interpret this syntax error message?

You've tabbed the make syntax lines, so make is passing them to your shell, get rid of the tabs (also reverse the conditional and remove the quotes)

all:
ifeq (,$(wildcard testFile))
    echo File is missing
else
    echo File exists
endif
