Error in ./cmake-release.sh

[gabekebab]

Hello,

I'm following the building instructions stated in the README file, but I'm having a problem in the first step after cloning the repository: ./cmake-release.sh

The following print was taken from the CMakeError.log, generated after the error appeared.

The error seems to be with not finding the -lpthreads... Did I do something wrong?

By the way, these are what I have in my system:
OS: Ubuntu 16.04 LTS
GCC: 5.4.0-6
Make: 4.1
CMake: 3.5.1
wget: 1.17.1
Flex: 2.6.0
Bison: 3.0.4

Best regards,
André
