cmake checking block unixODBC

[frederick623]

I found that the CMake/Modules/FindODBC.cmake is not able to find the libraries installed by unixODBC, because the file installed by latter on is named libodbc but the cmake checking only checks for unixodbc or iodbc.
Please check odbc instead.

I'd welcome a PR. Take a look at
