I'm not sure your fix is the best way.
AFAIK the cache works like this:
if a FIND_XXX() call is executed, the result if stored in the cache. If it 
succeeded, it will be "/usr/local/lib/libfoo.so" or something, if it failed 
it will be "foo-NOTFOUND".
When the FIND_XXX() command is executed the next time, the cache will be 
checked. If the value is "*_NOTFOUND", the check will be executed again. This 
is intentional, so that after installing a missing component it will be found 
automatically.

Do these checks actually consume a measurable amount of time ?

Bye
Alex
