I have been looking for a C++ Web Framework that would allow me to build a GUI Control Panel directly into a .dll plugin. In the past I have used Nancy Framework for .NET Projects which was exceptional (was my first time with this type of framework). I have found some good candidates based off of other Stack Overflow questions, however I am having trouble figuring out which, if any, have embedded web servers.
C++ Server Pages - This Looked Exceptional, but runs off of IIS or Apache.
CppCMS - Constantly recommended, but does it have an embedded server?
TreeFrog - Also recommended, but seems to have very broken documentation?
Which one of these would be recommended for a completely embedded solution? Ease of use would also be a huge plus, but I am willing to take the time to get it working provided it does what is needed. Thanks!
