BUG: Path to executables was found only after reconfiguring the project

When configuring the project a first time, the path to the executables used for the installation and the packaging were not set properly. CMake was trying to fin the executable but those were not yet built. One had to compile the code first, and then configure the project again to set the paths properly

STYLE: Useless ITK deprecated define removed.

The ITK_EXPORT define was set to nothing and had no
known remaining purpose.  It was removed to make the
over all code easier to understand.  There was,
understandably, a bit of confusion about the
need for this being pervasive in the code.

It is currently backwards compatible to have
this in code, but at some future point it will
be removed.
