Summary0014276: cmake --find-package doesn't handle debug/optimized/general keywords
DescriptionCMake find/config modules may return libraries prefixed with "debug", "optimized" or "general" keywords to link different libraries depending on the build type. These are handled specially by target_link_libraries. The --find-package mode treats them as libraries to link against instead.
Steps To ReproduceWith the Ubuntu system install of protobuf:

$ cmake --find-package -DNAME=Protobuf -DCOMPILER_ID=GNU -DLANGUAGE=CXX -DMODE=LINK
-rdynamic -loptimized -lprotobuf -ldebug -lprotobuf -ldebug

Having seen the feedback of this feature so far, I plan to change it so that it supports only find_package() in Config mode.
This will make things more reliable.
But this won't happen for 2.8.12.

Part of the issue seems to be brain dead searching for a debug library in FindProtobuf.cmake:

   find_library(${name}_LIBRARY
       NAMES ${filename}
       PATHS ${PROTOBUF_SRC_ROOT_FOLDER}/vsprojects/Release)
   mark_as_advanced(${name}_LIBRARY)

   find_library(${name}_LIBRARY_DEBUG
       NAMES ${filename}
       PATHS ${PROTOBUF_SRC_ROOT_FOLDER}/vsprojects/Debug)
   mark_as_advanced(${name}_LIBRARY_DEBUG)

   if(NOT ${name}_LIBRARY_DEBUG)
      # There is no debug library
      set(${name}_LIBRARY_DEBUG ${${name}_LIBRARY} PARENT_SCOPE)
      set(${name}_LIBRARIES ${${name}_LIBRARY} PARENT_SCOPE)
   else()
      # There IS a debug library
      set(${name}_LIBRARIES
          optimized ${${name}_LIBRARY}
          debug ${${name}_LIBRARY_DEBUG}
          PARENT_SCOPE
      )
   endif()


That seems very VisualStudio ? specific. On linux/unix it simply finds the same library twice.
