I have just tried to compile LibreCAD on a LinuxCNC installation, which is based on the (admittedly rather old) Ubuntu 10.04 LTS distribution.
I have found the hint in common.pri about custom.pro containing CXX_CPP11_FLAG, but the compilation still fails.

Here is what I did:

rli@cncsim:~/devel$ git clone https://github.com/LibreCAD/LibreCAD.git

rli@cncsim:~/devel$ cd LibreCAD/
rli@cncsim:~/devel/LibreCAD$ echo "CXX_CPP11_FLAG = -std=c++0x" > custom.pro
rli@cncsim:~/devel/LibreCAD$ qmake librecad.pro

I don't know if this is a specific C++11 syntax issue or if the compilation fails on more modern platforms too.
