How to use PreprocessingTool in Gradle?

You do it the same way you’re defining macros for the cppCompiler.

Here’s an example defining a macro for only shared libraries when building with MSVC:

gradle/gradle/blob/master/subprojects/docs/src/samples/native-binaries/c/build.gradle#L67


// END SNIPPET compiler-args


// START SNIPPET all-shared-libraries
// For any shared library binaries built with Visual C++,
// define the DLL_EXPORT macro
model {
binaries {
    withType(SharedLibraryBinarySpec) {
        if (toolChain in VisualCpp) {
            cCompiler.args "/Zi"
            cCompiler.define "DLL_EXPORT"
        }
    }
}
}
// END SNIPPET all-shared-libraries
