* Adding top-level CPACK option
* Setting CMAKE_BUILD_TYPE should always be Cache variables
This initializes CMAKE_CXX_FLAGS_RELEASE during project() correctly. With out
this, changes to CMakeLists.txt may result in a complete rebuild because
CMAKE_BUILD_TYPE wasn't in the cache before, and wasn't respected by project(),
but now it is.

* Always build deb and rpm packages where possible
* Searching for .ttf instead of hard-coding it's full path
