EnvironmentError: No tool named 'fastcpp': not a Zip file:

I am compiling some proprietary code and trying to build an image. Here I am getting an error of

EnvironmentError: No tool named 'fastcpp': not a Zip file:
File "/usr/lib/scons/SCons/Environment.py", line 1785:
tool = SCons.Tool.Tool(tool, toolpath, **kw)
File "/usr/lib/scons/SCons/Tool/__init__.py", line 105:
module = self._tool_module()
File "/usr/lib/scons/SCons/Tool/__init__.py", line 165:
raise SCons.Errors.EnvironmentError(m)

I downloaded the fastcpp from here but not able to understand how can I install it as it has some code files having .hpp extensions.

I have already install scons successfully.

Can anyone explain what is fastcpp and how to use it to fix above error?
