Сборка Poco 1.9.0 с модулем Crypto

Мне нужно собрать Poco 1.9.0 с clang для Android armeabi-v7a.

Строю вот так:

./configure --no-sharedmemory --no-wstring --config=Android-armeabi-v7a-clang --no-samples --no-tests --omit=Data,PageCompiler,ApacheConnector,CppParser,PDF,PocoDoc,ProGen,Encodings,CppUnit,MongoDB,Redis,SevenZip,Zip
make -j4
make install

Вот файл конфигурации для Android-armeabi-v7a-clang, который я создал:

ifeq ($(ANDROID_ABI),armeabi)
TOOL      = arm-linux-androideabi
ARCHFLAGS = -mthumb

Когда я пытаюсь построить его, я получаю несколько случаев этой ошибки:

include/Poco/Crypto/Crypto.h:30:10: fatal error: 'openssl/opensslv.h' file not found

Как я уже сказал ранее, я использую poco версии 1.9.0, clang версии 3.8.0 на Linux-машине. Сборка без модуля Crypto работает нормально. Спасибо за помощь
