Best way to check with CMake whether list containts a specific entry

Question

I want to check whether a lists contains a specific entry like in the following code snipplet:

macro(foo)
if ($(ARGN} contains \"bar\")
  ...
endif
endmacro()
         


        

Answer 1

Fewer lines:

if (";${ARGN};" MATCHES ";bar;")
  #  ...
endif()

But see the IN_LIST syntax from @sakra for a more-modern syntax.
