When I set Content-Type header to multipart/form-data and add data to

You might find that using curl_formadd() and CURLOPT_HTTPPOST is easier than
crafting your own multipart post like this...
2) If I don't set Content-Length then it doesn't hang, makes the post.
However receiving side doesn't get data (content length 172 but should
be 134610
Without Content-Length you need another way to tell the server the request
ends (like Connection: close or chunked-encoding). With Content-Length you
need to make sure the value is correct.
file.open("/c/nginx/0/11/0000000110",ios_base::binary);
post_size = file.tellg();
^^^ this is not correct. That's the file size, not the post size. Aha! Have
you already created the file to contain the entire multipart payload in
correct format? Then it should be correct.
Compare with what curl -F would send.
file.seekg(0,ios::beg);
post_string = new char[post_size];
file.read(post_string,post_size);
You're reading the entire file into memory before sending it, which libcurl's
multipart API doesn't forces you to do...

Content-Disposition: form-data; name="fileToUpload"; filename="Capture.PNG"
Content-Type: image/png

No ending boundary? That looks like a malformed multipart.
