I think you're looking for 


  file(GENERATE
    OUTPUT "${CMAKE_CURRENT_BINARY_DIR}/dirInstallScript.cmake"
    CONTENT   " 
  if (CMAKE_INSTALL_CONFIG_NAME STREQUAL RELEASE)
    file(INSTALL DESTINATION
      \"\${CMAKE_INSTALL_PREFIX}/share/myproj\" TYPE DIRECTORY
      FILES \"$<TARGET_FILE_DIR:mn>/MyDir\")
  endif()")

  install(SCRIPT "${CMAKE_CURRENT_BINARY_DIR}/dirInstallScript.cmake")


Thanks,

Steve.
