[CMake] adding extra target to CMakeLists.txt

[Ryan Pavlik]

Load them from the target using the target properties:
get_directory_property(_include_dirs INCLUDE_DIRECTORIES)
set(_includeflags)
foreach(_dir ${_include_dirs})
     list(APPEND _args "${YOURTOOL_INCLUDEPATH_ARG}${_dir}")
endforeach()

get_target_property(_sources "${_targetname}" SOURCES)
set(_files)
foreach(_source ${_sources})
     get_source_file_property(_lang "${_source}" LANGUAGE)
     get_source_file_property(_loc "${_source}" LOCATION)
     if("${_lang}" MATCHES "CXX")
         list(APPEND _files "${_loc}")
     endif()
endforeach()

Repeat with COMPILE_DEFINITIONS (and the per-config ones, if you want to 
make it fancy) and COMPILE_FLAGS.


Also, you may want to note: trying to troubleshoot your CMake files by 
looking at the generated Makefiles is generally a futile endeavor - 
better to just try a make VERBOSE=1 to see what's actually being run.  
(There's a lot of clutter in the generated makefiles to support all the 
slick stuff CMake gives us for free.)
