[QBS] Properties for multiple conditions

[Jake Petroules]

Hi Markus,

Properties items are indeed interpreted similarly to an if-else chain. To achieve the behaviour you are looking for, you may use the following:

cpp.defines: {
	var defines = ["MY_DEFINE"];
	if (qbs.targetOS.contains("linux"))
		defines.push("LNX_DEFINE");
	if (qbs.targetOS.contains("windows"))
		defines.push("WIN_DEFINE");
	if (qbs.buildVariant.contains("debug"))
		defines.push("DBG_DEFINE");
	return defines;
}
