Correct, this is expected behavior. The details can be found here:

http://www.vtk.org/Wiki/CMake_2.6_Notes#Package_Configuration_Files

Towards the end of the section it is stated that the
/install/lib/cmake/orocos-rtt folder is searched by default only on cmake >=
2.6.3. This is, however, the suggested practice, and on the case of rtt, it
nicely separates the coexisting pkgconfig and cmake package configuration
files in appropriately named folders.

Having said that, it looks like this issue should be documented in the
"getting started" parts of the documentation to prevent similar future
confusions.
