libcpr/cpr 1.6.0

cpr v1.6.0

on GitHub

In this release the CMake integration has been refactored to fix a bunch of SSL issues.
During this change all relevant CMake variable names changed.
Here are the new ones:

-- =======================================================
--   CPR_GENERATE_COVERAGE: OFF
--   CPR_CURL_NOSIGNAL: OFF
--   CPR_USE_SYSTEM_GTEST: OFF
--   CPR_FORCE_USE_SYSTEM_CURL: OFF
--   CPR_ENABLE_SSL: ON
--   CPR_FORCE_OPENSSL_BACKEND: OFF
--   CPR_FORCE_WINSSL_BACKEND: OFF
--   CPR_BUILD_TESTS: ON
--   CPR_BUILD_TESTS_SSL: ON
-- =======================================================

Documentation for those can be found here: https://github.com/whoshuu/cpr/blob/aac5058a15e9ad5ad393973dc6fe44d7614a7f55/CMakeLists.txt#L30-L40

If neither CPR_FORCE_OPENSSL_BACKEND nore CPR_FORCE_WINSSL_BACKEND has been set to ON, CMake will try to automatically detect the best SSL backend for your system (WinSSL - Windows, OpenSSL - Linux & Mac, ...).

How to build on Windows

With WinSSL

mkdir build
cd build
cmake .. -DCPR_BUILD_TESTS_SSL=OFF # SSL test are only supported with OpenSSL
cmake --build .

With OpenSSL

mkdir build
cd build
cmake .. -DCPR_FORCE_OPENSSL_BACKEND=ON # Disable auto detect and force OpenSSL
cmake --build .
