Cc: [email protected] Subject: Re: [CMake] Issues with execute_process and svn It boils down to this: set(args --username MyUserName) # sets args to a list with two elements set(args "--username MyUserName") # sets args to a list with one element: a string containing a space execute_process(COMMAND blah ${args}) # calls the command "blah" expanding the n-element CMake list variable "args" such that each list element is a separate arg to execute_process, and hence a separate arg to the blah command HTH, David On Wed, Jul 13, 2011 at 4:20 PM, <[email protected]> wrote: > That works!
