Simple libcurl wrapper for when you need to GET a website with minimum effort.

This is _not_ supposed to be a package on its own, but a thing you drop into
your project.

I made this because the curl wrapper I used before is no longer maintained and
the other wrappers are either incomplete or unmaintained as well.

== Example program

[source,cpp]
--------------------------------------------------------------------------------
#include "curl_wrapper.hpp"
#include <iostream>

namespace cw = curl_wrapper;

cw::CURLWrapper curl;
const auto answer{curl.make_http_request(cw::http_method::GET,
                                         "http://example.com/")};
if (answer)
{
    std::cout << answer;
}
--------------------------------------------------------------------------------

== Use with CMake

Drop this project into a subfolder in your project tree. It will be compiled as
a static library.

[source,cmake]
--------------------------------------------------------------------------------
add_subdirectory(curl_wrapper)

add_executable(test)
target_link_libraries(test PRIVATE curl_wrapper)
--------------------------------------------------------------------------------

.CMake options:
- `-DWITH_TESTS=YES` compiles the tests.

== Dependencies

- C++17
- CMake >=3.9
- libcurl >= 7.52
