[Insight-users] CMake prompting

[Luis Ibanez]

Hi Carlos,


A common method is to do:


   FIND_PATH( CARLOS_DIR   filewithUniqueName )

   IF(NOT CARLOS_DIR)
     MESSAGE("you should provide the directory XX")
   ENDIF(NOT CARLOS_DIR)


   INCLUDE_DIRECTORIES(
       ${CARLOS_DIR}
       )


Note that the second argument that the FIND_PATH()
command should be the name of a file that you expect
to be present in the "CARLOR_DIR" location.  Typically
you want to use a file name that is very characteristic
of that specific directory (e.g. a filename that you
don't expect to find (almost) anywhere else).


For more details on this command, type

     cmake    --help-command FIND_PATH




     Regards,


        Luis
