To add this tool to your project:
def options(conf):
        opt.load('codelite')

It can be a good idea to add the sync_exec tool too.

To generate solution files:
$ waf configure codelite

To customize the outputs, provide subclasses in your wscript files:

from waflib.extras import codelite
class vsnode_target(codelite.vsnode_target):
        def get_build_command(self, props):
                # likely to be required
                return "waf.bat build"
        def collect_source(self):
                # likely to be required
                ...
class codelite_bar(codelite.codelite_generator):
        def init(self):
                codelite.codelite_generator.init(self)
                self.vsnode_target = vsnode_target

The codelite class re-uses the same build() function for reading the targets (task generators),
you may therefore specify codelite settings on the context object:

def build(bld):
        bld.codelite_solution_name = 'foo.workspace'
        bld.waf_command = 'waf.bat'
        bld.projects_dir = bld.srcnode.make_node('')
        bld.projects_dir.mkdir()


ASSUMPTIONS:
* a project can be either a directory or a target, project files are written only for targets that have source files
* each project is a vcxproj file, therefore the project uuid needs only to be a hash of the absolute path
