[Cmake] CMake 1.4, NMake makefile, problem with "jump over" t o build requ ired lib

[Bill Hoffman]

I agree with Jim, the order of your SUBDIRS seems to be wrong.
In VTK, we build all the libraries, then jump to the Examples and Testing.

However, you have found a bug.   If the LIBRARY_OUTPUT_PATH is not set,
the jump to build does not work.   Did this work in CMake 1.2?
