Did you add meta-networking to bblayers.conf?

Probably because the dependency ended up on a package you didn't 
actually instally.  Also RDEPENDS are not in the sysroot, so the curl 
build wouldn't have been able to see nghttp2, you meant to add it to 
DEPENDS.

Adding the library to the image won't change the curl library which has 
already been built without nghttp2.


Looking at the curl recipe, nghttp2 support is there but disabled out of 
the box, so you just need to turn the support on. The recipe has:

PACKAGECONFIG[nghttp2] = "--with-nghttp2,--without-nghttp2,nghttp2"

The documentation covers the methods available to turn on/off 
PACKAGECONFIG options:
