Comment (by ballapete):

 With two little paches and `configure.cppflags-append -D_NETINET_TCP_H_=1`
 the `configure` step came quite far and reached to:

 The two `CMake*.log` files do not seem to contain anything useful, in
 `CMakeError.log` I only find:

 The mentioned `CMakeLists.txt` has:

 I am lost now…
