Background

I am trying to use libcurl in a program.

I am cross compiling this program for the Omega 1 on my laptop using the official guide.

I am having issues figuring out how to obtain the header files and the library for libcurl on the Omega 1 for cross compilation.

Issues

If I compile the program for my host OS then my native toolchain will find the necessary libcurl files. I am not sure if these same files can be used to cross compile a program for the Omega 1.

I can use opkg to install libcurl on the Omega. However I believe I need the files on my laptop instead.

If I try to install the libcurl package on my laptop inside the OpenWRT git repository by running:

scripts/feeds update -a
scripts/feeds install libcurl

It does not seem to work for 2 reasons.

First because that the install command shows this output:

WARNING: Makefile 'package/network/utils/curl/Makefile' has a dependency on 'libgnutls', which does not exist
WARNING: Makefile 'package/network/utils/curl/Makefile' has a dependency on 'libopenldap', which does not exist
WARNING: Makefile 'package/network/utils/curl/Makefile' has a dependency on 'libidn2', which does not exist
WARNING: Makefile 'package/network/utils/curl/Makefile' has a dependency on 'libssh2', which does not exist
WARNING: Makefile 'package/boot/kexec-tools/Makefile' has a dependency on 'liblzma', which does not exist
WARNING: Makefile 'package/network/services/lldpd/Makefile' has a dependency on 'libnetsnmp', which does not exist
WARNING: Makefile 'package/network/utils/nftables/Makefile' has a dependency on 'jansson', which does not exist

And second because the cross compile toolchain still can't find the curl/curl.h.

Question

How would I go about obtaining the files needed to cross compile a binary for the Omega 1 with libcurl?
