Ya you're right, It should be picked up. For what it's worth, here's our gradle config, (which ends up passing the correct flags to cmake for building gnustep): defaultConfig { applicationId "com.noodlecake.ssg4" minSdkVersion 21 targetSdkVersion 28 versionCode 28 versionName "1.0.0" testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner" externalNativeBuild { cmake { cppFlags "-std=c++14 -frtti -fexceptions -fconstant-string-class=NSConstantString" cFlags "-DANDROID -fconstant-string-class=NSConstantString" arguments "-DCMAKE_VERBOSE_MAKEFILE=ON", "-DANDROID_STL=c++_static", "-DANDROID_DISABLE_FORMAT_STRING_CHECKS=TRUE" } } ndk { // Specifies the ABI configurations of your native // libraries Gradle should build and package with your APK. //abiFilters 'x86', 'x86_64', 'armeabi', 'armeabi-v7a', // 'arm64-v8a' abiFilters 'armeabi-v7a' } }
