[CMake] EXIT() or RETURN() commands

[Filipe Sousa]

Hi,

I have some FindFoo.cmake scripts that uses big IF commands:

FIND_PROGRAM(FOO_EXEC ...)
IF(FOO_EXEC)
  # a lot of code
ENDIF()

With a RETURN or EXIT command I could remove some nested code

FIND_PROGRAM(FOO_EXEC ...)
IF(NOT FOO_EXEC)
  RETURN() or EXIT()
ENDIF()
# a lot of code

What do you think?
