[CMake] cache variable prevents FIND_LIBRARY to be called again :/

[Tristan Carel]

Hi,

The documentation of `FIND_LIBRARY' specify:
"Once one of these calls succeeds the result variable will be set and
stored in the cache so that neither call will search again."

Is there a way to avoid this behavior? I've got a FIND_LIBRARY whose
search locations depends of the result of a EXECUTE_PROCESS so this
FIND_LIBRARY needs to be performed each time I run `configure'.

Is there a way to remove an entry from the cache?

Thx
