Por lo que he leído tiene que ver con el uso de la librería en modo static o dynamic y entiendo que que la librería está instalada como estática.</div>
<div> En la propia página de la librería explican esto:</div>
<div><a href="https://curl.haxx.se/docs/install.html" class="OWAAutoLink" id="LPlnk478247" previewremoved="true">https://curl.haxx.se/docs/install.html</a></div>

<h2 style="border-bottom: 1px solid black; font-family: arial, helvetica, ariel, sans-serif;">
Important static libcurl usage note</h2>
<p style="font-family: arial, helvetica, ariel, sans-serif; font-size: 20px;">When building an application that uses the static libcurl library on Windows, you must add <code>-DCURL_STATICLIB</code> to your <code>CFLAGS</code>. Otherwise the linker will look
for dynamic import symbols.</p>
<br>
<br>
Cuando cosntruyes una aplicación que utiliza la librería lib Curl estática en Windows, debes añadir -DCURl_STATICLIB a tus CFLAGS. Si no el linker importará simbolos dinámicos.</div>

Antes de haber hecho eso, había probado a<span style="font-family: Calibri, Helvetica, sans-serif, EmojiFont, "Apple Color Emoji", "Segoe UI Emoji", NotoColorEmoji, "Segoe UI Symbol", "Android Emoji", EmojiSymbols; font-size: 16px;"> anadir </span><span style="font-family: Calibri, Helvetica, sans-serif, EmojiFont, "Apple Color Emoji", "Segoe UI Emoji", NotoColorEmoji, "Segoe UI Symbol", "Android Emoji", EmojiSymbols; font-size: 16px;">-DCURl_STATICLIB
en: botón secundario en el proyecto/Build options/Complier settings/Other complier options y me devolvió una lista de 50 errores, pero no los había compiado y como no se deshacer lo que hice en <span style="font-family: Calibri, Helvetica, sans-serif, EmojiFont, "Apple Color Emoji", "Segoe UI Emoji", NotoColorEmoji, "Segoe UI Symbol", "Android Emoji", EmojiSymbols; font-size: 16px;">Settings/Compiler/Compiler
