link error: cannot find -lcurl

[remyers]

Fresh install of Ubuntu 20.04 I get the following link error using ./gradlew :build after following build steps from BUILD.md . Any tips why the curl library is not being found?

It seems like libcurl is installed

$ /sbin/ldconfig  -p | grep curl
        libcurl.so.4 (libc6,x86-64) => /lib/x86_64-linux-gnu/libcurl.so.4
        libcurl-gnutls.so.4 (libc6,x86-64) => /lib/x86_64-linux-gnu/libcurl-gnutls.so.4

Our tests use ktor-client which on linux depends on ktor-client-curl-linuxx64.
It can be fixed with sudo apt install libcurl4-openssl-dev

@sstone I couldn't find anything in the build docs about that dependency. Should I do a PR to add it, or perhaps there is a link to the ktor-client dependencies I should add to BUILD.md ?

[remyers]

Thanks, btw, that did fix it!

[sstone]

I think that it's the only library that needs to be installed (on linux, it's not needed on macOS) but I will double check. AFAICT it's not documented anywhere....

Is this still an issue? If so, can you open a PR to fix this?
