How to set option for compiler in premake4?

Question

How can I set option that is available for particular compiler in premake4?

For instance only in Visual Studio set "Whole Program Optimization"? This option is not available in GCC...

Answer 1

If you are using the development version of Premake, you can set the link-time optimization flag:

flags { "LinkTimeOptimization" }

If you are using the stable version, you can get the same effect by setting the command line flag explicitly for Visual Studio:

configuration "vs*"
    buildoptions { "/GL" }
