No, you surely don't want to do that. From the documentation of it (cmake --
help-command file):

       We do not recommend using GLOB to
       collect a list of source files from your source tree.  If no
       CMakeLists.txt file changes when a source is added or removed then the
       generated build system cannot know when to ask CMake to regenerate.

Simple solution: do something like find . -type f -name \*.cc | sed 's,^\./,,' 
>> CMakeLists.txt and move the result at the correct place in that file.
