Those three options affect INSTALL_NAME_DIR the same way they affect 
INSTALL_RPATH.  This install_name business is (approximately) the OSX 
equivalent to RPATH.

Basically yes.  When building the install_name is set to the build dir. 
  The target property INSTALL_NAME_DIR is used when installing.  This 
property is initialized when the target is created using the contents of 
the variable CMAKE_INSTALL_NAME_DIR.
