Build RESTful API client example for WASM

[ahatstat]

I was able to build the RESTful API client example for desktop Linux Qt version 6.8.1, but when i tried to build it for WASM (single threaded) I got complaints about missing header files.

fatal error: 'QtNetwork/qrestaccessmanager.h' file not found

I used the network installer to install Qt. Indeed qrestaccessmanager.h is not in wasm_singlethread/include/QtNetwork/ nor are any http related header files. The file is found in other adjacent installations. Does that mean that http features are not supported for WASM single threaded builds?

It appears that all http features are disabled in single threaded web assembly builds as seen here.

qt_feature("http" PUBLIC
    SECTION "Networking"
    LABEL "HTTP"
    PURPOSE "Provides support for the Hypertext Transfer Protocol in QNetworkAccessManager."
    CONDITION QT_FEATURE_thread

Bummer. Accessing a Restful API from a WASM application seems like a common use case. Other than switching to multithreaded (which requires https) any suggestions on porting the qrestaccessmanager to single threaded?

Strange, I know for a fact that QNetworkAccessManager works on wasm, so you may want to use that instead.
