Building libssh on RHEL7

[Neil Youngman <neil.youngman@xxxxxxxxxxxx>]

I'm trying to build libssh 0.9.3 on RHEL7

The INSTALL document says that it requires cmake >= 2.6.0 but trying to 
build with 2.8.1 it says the requirement is 3.3

Using an updated cmake, the build fails with:

[ 44%] Building C object src/CMakeFiles/ssh.dir/libcrypto.c.o

    __attribute__((format(__printf__, 1, 2), __unused__));

I'm guessing I need a newer compiler (gcc 4.8) or a newer version of one 
of the libraries?
