Andy Green 53d195022f cmake: Enable WITH_MINIMAL_EXAMPLES by default 
Although many of the examples must be run from the example directory as
cwd, everyone getting started probably wants to try the examples, cmake
knows how to do it, so let's enable it by default.

lws minimal http client POST

This example demonstrates a multipart POST to

https://libwebsockets.org/testserver/formtest

setting both a form variable and uploading a short file.

The result of the POST form processing is captured and displayed in a hexdump.

This is programmatically POSTing to the same form you can access at

https://libwebsockets.org/testserver

in the "POST" tab with file upload.

By default the client action occurs using http/2 if your lws was built with -DLWS_WITH_HTTP2=1.

build

 $ cmake . && make

usage

 $ ./lws-minimal-http-client-post
