Alex,

Thank you again.  I updated the projects per your teaching.  The only
place I had to guess was here:

INSTALL(
  FILES
    ${CMAKE_CURRENT_BINARY_DIR}/helloConfig.cmake
  DESTINATION
    ${hello_DIRNAME_lib}
  )

With respect to this INSTALL directive, I have three questions:

1. Is it needed?  [Apparently the answer is yes]

2. Is ${CMAKE_CURRENT_BINARY_DIR}/helloConfig.cmake the appropriate
way for me to reference this file?  I got this from kdelibs.git.

3. Is ${hello_DIRNAME_lib} (aka
/usr/local/lib/hello-1.1/helloConfig.cmake) the correct place to
install helloConfig.cmake?  kdelibs.git puts it somewhere else
("${CMAKECONFIG_INSTALL_DIR}" which I guessed corresponds to the weird
location /usr/local/hello/).

Thank you again,

Chris
