You can't. You have to use TOLOWER and add an extra variable if you can't mutate your existing variable value...<div><br></div><div>set( file "Makefile" )</div><div>string( TOLOWER "${file}" file_lower )</div>
<div>if( file_lower STREQUAL "makefile" )</div><div>...</div><div><br><br><div class="gmail_quote">On Thu, Jun 7, 2012 at 6:37 PM, Robert Dailey <span dir="ltr"><<a href="mailto:rcdailey.lists@gmail.com" target="_blank">rcdailey.lists@gmail.com</a>></span> wrote:<br>
