How Can I use CPR library with Android(NDK)?

I am trying to use CPR in android. This is my src/main/cpp directory's structure:

cpr/ 
native-lib.cpp
CMakeLists.txt

note: cpr/ directory is generated by running this command git clone --recurse-submodules https://github.com/whoshuu/cpr.git

And this is the content of CMakeLists.txt in src/main/cpp directory:

cmake_minimum_required(VERSION 3.4.1)
add_library(
        native-lib
        SHARED
        native-lib.cpp
)
find_library(
        log-lib
        log
)

add_subdirectory(cpr)
target_link_libraries(
        native-lib
        cpr
        ${log-lib}
)

But I get this error when I build and run the code:

Could NOT find OpenSSL, try to set the path to OpenSSL root folder in the
  system variable OPENSSL_ROOT_DIR (missing: OPENSSL_CRYPTO_LIBRARY
  OPENSSL_INCLUDE_DIR)

You can first look at this stack-overflow answer: Visit reference - find open-ssl.

If you're on Linux-OS - this worked!. You can install open-ssl via terminal as:

  • sudo apt-get install libssl-dev

Otherwise, you have to solved as follows: You have to open the CMakeCache.txt file in source-directory, find the line:

  • OPENSSL_INCLUDE_DIR:PATH=OPENSSL_INCLUDE_DIR-NOTFOUND

Visit reference: find-open-ssl, then change it to with your openssl location inside source-directory as follows:

  • OPENSSL_INCLUDE_DIR:PATH=/usr/local/opt/openssl/include

For further learing in detail: Visit reference- open-ssl-during-cmake
