fastddsgen internally calls 'cpp' (the C preprocessor) to resolve
include directives, include guards, etc. See
541129f6e7/src/main/java/com/eprosima/fastdds/fastddsgen.java (L1423)
Make 'cpp' available from the fastddsgen wrapper script. Use the
unwrapped 'cpp', because the wrapped one passes additional parameters,
which make the produced output incompatible with fastddsgen (string out
of bounds exception).
Fixes the error when using IDL files with includes:
```

eProsima Fast DDS-Gen is a Java application that generates
|
|
eProsima Fast DDS C++ or Python source code using the data types
|
|
defined in an IDL (Interface Definition Language) file. This
|
|
generated source code can be used in any Fast DDS application in
|
|
order to define the data type of a topic, which will later be
|
|
used to publish or subscribe.
