[CMake] Problems with ExternalProject_Add and tar.gz files

[Luigi Calori]

I got exactly the same error in doing something similar:
it is the untar phase based on cmake that seem to fail on some kind of tar:
in the untar phase, externalProject uses cmake -E tar xvf <tar file>
and this is the part that fail.
if I issue the command:

 >cmake -E tar xzf boost-1.41.0.cmake0.tar.gz
or unpack and
cmake -E tar xf boost-1.41.0.cmake0.tar

got the same error
CMake Error: Problem with tar_extract_all(): Invalid argument

It seem somehow related to some kind of tar version or content:

for example it happened to me also getting the latest pycrypto 
http://ftp.dlitz.net/pub/dlitz/crypto/pycrypto/pycrypto-2.1.0.tar.gz

Probably we should issue a bug
