Casablanca root path hint for Unix in FindCasablanca.cmake

[rdeterre]

Hi,

I am wondering if the line 43 of FindCasablanca.cmake shoud set the _CASABLANCA_ROOT_HINTS_AND_PATHS variable instead of _CASABLANCA_ROOT_HINTS. It seems that the latter is left unused after it's assignment.

Also, is the license for this repo the same as the one for FreeRDP? I'd like to re-use FindCasablanca.cmake in personal projects.

Thanks !

Romain
