Currently other members on my project have a variable in their cache named FOO_BAR. I renamed it to Some_Foo_Bar. It would be unmanageable to have to create a conference call or send out an email to everyone saying "Hey, delete your cache!". How can I programmatically force this variable to be renamed, while still retaining its previous value? Of course I could do this:<div>
<br></div><div>option( Some_Foo_Bar "Does a lot of foo..." )</div><div><br></div><div>if( FOO_BAR )</div><div> set( Some_Foo_Bar ${FOO_BAR} )</div><div> unset( FOO_BAR CACHE )</div><div>endif()</div><div><br></div>
<div>But is this the recommended path?</div>
