Visual Studio Preprocessor - access compiler flags - c++

Question

I am currently converting a Qt project from being .pro file based to Visual Studio based.
In the original .pro file I have used the following
LIBSTR = '\\"$${LIBS}\\"'
DEFINES += LIBRARIES=\"$${LIBSTR}\"
Which allows me to see what libraries were used in my application.
I would like to replicate this in Visual Studio but cannot see how to do this.

Answer 1

1) Add the configure.h to the project
#pragma once
#define LIBRARIES TEXT("")
2) Add $${LIBS} to the Project properties -> Linker -> Input -> Additional Dependencies section.
3) Add to the Project properties -> Build Events -> Pre-Build Event a script like:
cscript /nologo configure.js $(ProjectPath) $(ConfigurationName) $(PlatformName)
configure.js:
var proj = WScript.Arguments(0);
var conf = WScript.Arguments(1);
var platf = WScript.Arguments(2);
var configFile = "configure.h";
try {
var doc = new ActiveXObject("msxml2.DOMDocument.6.0");
doc.async = false;
doc.resolveExternals = false;
doc.validateOnParse = false;
doc.load(proj);
var node = doc.selectSingleNode("//Configuration[#Name=\""+conf+"|"+platf+"\"]/Tool[#Name=\"VCLinkerTool\"]");
var attr = node.attributes.getNamedItem("AdditionalDependencies");
var libStr = attr ? attr.value : "";
var fso = new ActiveXObject("Scripting.FileSystemObject");
var aFile = fso.GetFile(".\\" + configFile);
var fStream = aFile.OpenAsTextStream(1);
var re = new RegExp("^\\s*#\\s*define\\s+LIBRARIES\\s+");
var done = false;
var text = "";
while (!fStream.AtEndOfStream) {
var aStr = fStream.ReadLine();
if (!done && re.test(aStr)) {
aStr = "#define LIBRARIES TEXT(\"" + libStr.replace(/(\\|")/g, "\\$1") + "\")";
done = true;
}
text += aStr + "\n";
}
fStream.Close();
fStream = aFile.OpenAsTextStream(2);
fStream.Write(text);
fStream.Close();
} catch (e) {
WScript.Echo("Error:");
WScript.Echo(e.description);
WScript.Quit(1);
}
WScript.Echo("Done");
WScript.Quit(0);
Then after you'll start the build the configure.h file will be updated and LIBRARIES will contain all libs you defined for the current build configuration and platform.
