Build with different c++ compiler

[Kopernikus]

In the terminal I always build with
g++-mp-4.7 -std=c++11 -fopenmp prog.cpp -o prog.exe

but if I build in sublime text 2 with
"cmd": ["bash", "-c", "g++-mp-4.7 -std=c++11 -fopenmp '${file}' -o '${file_path}/${file_base_name}' && '${file_path}/${file_base_name}'"]

sublime text tells me it can't find g++-mp-4.7 ???? what is going on????
