Visual Studio - Where to define custom path macros?

Question

I just opened someone else\'s Visual Studio project and in their build properties they have a few custom path macro\'s they are using for their include and lib directories.

Answer 1

Try the other way without the hassle adding to each Property Sheet

Go to Windows OS System Properties > Environment Variables, just New and input the Variable e.g.: MY_PATH and value e.g.: D:\Dev_Path\

after that you have to restart your Visual Studio, you should be able to have ${MY_PATH} in macro list

p/s: just notice Jason Williams answered above is the OS Environment Variables method
