Yes, because your generator claims to produce target of type CPP, and
while several extensions of source files can be mapped to CPP type, when
generating targets, CPP is associated with .cpp extension, so Boost.Build
believe that tool should create file $(target).cpp

You might want to create a custom generator class and force specific name
when creating targets -- like:

        [ new file-target $(name).cc exact : ... ]

There example of custom generator class somewhere in example/ directory
