Do you have Xcode installed？

Normally you can find your iOS SDKs in /Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer/SDKs/.

Maybe I write wrong? Trouble you to help！

The default search path is determined by command /usr/bin/xcode-select -p. It prints /Applications/Xcode.app/Contents/Developer on my Mac. You can check if this command outputs the right thing.

Moreover, you can manually set CMAKE_IOS_SDK_ROOT yourself. Open build-protobuf-3.1.0.sh, find line 181 (the cmake * line in function build-iPhoneOS). Then add a -DCMAKE_IOS_SDK_ROOT=/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer to cmake options as bellow:

cmake ../cmake -DCMAKE_INSTALL_PREFIX=../../protobuf-$TARGET\
    -DCMAKE_TOOLCHAIN_FILE="../../ios-cmake/toolchain/iOS.cmake" \
    -DCMAKE_IOS_SDK_ROOT="/Applications/Xcode.app/Contents/Developer/Platforms/iPhoneOS.platform/Developer" \
    -DIOS_PLATFORM=OS \
    -DCMAKE_CXX_FLAGS="-fembed-bitcode" \
    -Dprotobuf_BUILD_TESTS=OFF \
    -Dprotobuf_BUILD_SHARED_LIBS=OFF \
    -Dprotobuf_WITH_ZLIB=OFF
