Hello I am using a roughly new cocos2dx project android studio project and everything works fine until i add in #include <curl/curl.h> and then i get the following error.
vtls/openssl.c:(.text.ossl_connect_common+0xbac): undefined reference to `PKCS12_parse'

it seems like a linker error but i am confused because doesn’t the android.mk in the external/curl/android folder already link curl and the respective openssl?
