[CMake] some helper targets ?

How about

# helper target to remove cache
ADD_CUSTOM_TARGET(cmclean ${CMAKE_COMMAND} -E remove
${CMAKE_CACHEFILE_DIR}/CMakeCache.txt
${CMAKE_CACHEFILE_DIR}/CMakeFiles/CMakeSystem.cmake
${CMAKE_CACHEFILE_DIR}/CMakeFiles/CMakeCXXCompiler.cmake
${CMAKE_CACHEFILE_DIR}/CMakeFiles/CMakeCCompiler.cmake)

# helper target to remove reinit from scratch
ADD_CUSTOM_TARGET(reinit ${CMAKE_COMMAND} ${CMAKE_SOURCE_DIR})
ADD_DEPENDENCIES(reinit cmclean)

Now with this rebuild_cache would rebuild the cache
without tests and reinit will rebuild the cache from scratch.
Me too, I think this would be nice to have as default.

And those two I find usefull as well to switch
build type via the makefiles

ADD_CUSTOM_TARGET(set_debug ${CMAKE_COMMAND}
-DCMAKE_BUILD_TYPE:STRING=debug ${CMAKE_CURRENT_SOURCE_DIR})
ADD_CUSTOM_TARGET(set_release ${CMAKE_COMMAND}
-DCMAKE_BUILD_TYPE:STRING=release ${CMAKE_CURRENT_SOURCE_DIR})

By the way it would be nice if one could have a doc string for targets
because users that did not create the CMakeList.txt
don't understand the different targets that might be available.
