Whenever I use cpr into my ixx module I just get an LNK2001 unresolved external symbol _Cnd_timedwait_for and can't build my project.
Build started at 5:37 PM...

When I comment the return lines in sendRequest it compiles.. But I need the response..
Example/How to Reproduce
Create an ixx(C++20) Module with the following code:
export module Req;
import <string>;
import <unordered_map>;
import <cpr/cpr.h>;
namespace Req {
enum class Method {
GET,
POST
};
static constexpr const char* baseURL = "https://example.com";
class Request {
public:
Request(Method method, const std::string& endpoint)
: method_(method), endpoint_(endpoint) {}
void addHeader(const std::string& key, const std::string& value) {
headers_[key] = value;
}
void addFormData(const std::string& key, const std::string& value) {
formData_[key] = value;
}
cpr::Response sendRequest() const {
cpr::Url url = cpr::Url{ baseURL + endpoint_ };
if (method_ == Method::GET) {
url = addParametersToUrl(url);
return cpr::Get(url, buildRequestOptions());
}
else if (method_ == Method::POST) {
cpr::Parameters parameters;
for (const auto& pair : formData_) {
parameters.Add({ pair.first, pair.second });
}
return cpr::Post(url, buildRequestOptions(), parameters);
}
// Default to GET if method is invalid
return cpr::Get(url, buildRequestOptions());
}
private:
Method method_;
std::string endpoint_;
std::unordered_map<std::string, std::string> headers_;
std::unordered_map<std::string, std::string> formData_;
cpr::Url addParametersToUrl(const cpr::Url& url) const {
// Implement parameter handling logic if needed
return url;
}
cpr::Header buildRequestOptions() const {
cpr::Header options;
for (const auto& pair : headers_) {
options.insert({ pair.first, pair.second });
}
return options;
}
};

Where did you get it from?
