I see one typo:

```diff
+set(CMAKE_PREFIX_PATH CHACHE ${OUTPUT_PATH})

```

Even the previous code looks odd as it does `CACHE STRING ${OUTPUT_PATH}` which makes `OUTPUT_PATH` the documentation string for the cache entry.

I don’t see an error here. Is there other output that indicates an error available?

strange, after a bit playing around he told me the real error and now it’s working again, thanks for the fast reply. so you mean i should change CHACHE to STRING right ?

It depends on what you want. If you want it in the cache (which I don’t recommend), then it is a typo for `CACHE`. See [the docs for `set(CACHE)`](https://cmake.org/cmake/help/latest/command/set.html#set-cache-entry) for the supported syntax.
