ubuntu 20.04 install curl / microhttpd

[R C]

Hello,


when I install curl/curldev it appears for example that curl.h gets 
installed in /usr/include//aarch64-linux-gnu/curl instead of 
/usr/include/curl


similar for the libraries.


also:

rocr at f007th:~/Projects$ sudo apt-get install libcurl-dev

Package libcurl-dev is a virtual package provided by:
   libcurl4-openssl-dev 7.68.0-1ubuntu2.2
   libcurl4-nss-dev 7.68.0-1ubuntu2.2
   libcurl4-gnutls-dev 7.68.0-1ubuntu2.2
You should explicitly select one to install.

E: Package 'libcurl-dev' has no installation candidate


Or am I just installing the wrong packages?
