CGAL flag options with Qt

[bryanxito]

Hi guys I need help to pass this CGAL command into a Qt project:

g++ -frounding-math -O3  -lCGAL -lgmp main.cpp

g++ -frounding-math -O3  -lCGAL -lgmp main.cpp

To copy to clipboard, switch view to plain text mode 

So far the libraries are linked with this:

LIBS += -L/lib64 -lgmp -lCGAL

LIBS += -L/lib64 -lgmp -lCGAL

To copy to clipboard, switch view to plain text mode 

But I can't pass the flags: -frounding-math -O3

Any ideas? (=
