Title: it's all in the curly braces... apparently.

This :
```
IF(NOT DEFINED ${CYCLUS_ROOT_DIR})
SET(CYCLUS_ROOT_DIR "$ENV{CYCLUS_ROOT_DIR}")
ENDIF(NOT DEFINED ${CYCLUS_ROOT_DIR})
```

is incorrect, and therefore produces illogical results. This, however, is the way it's supposed to work :

```
IF(NOT DEFINED CYCLUS_ROOT_DIR)
SET(CYCLUS_ROOT_DIR "$ENV{CYCLUS_ROOT_DIR}")
ENDIF(NOT DEFINED CYCLUS_ROOT_DIR)
```
