If you're only changing `/etc/wget` (Hopefully `/etc/wgetrc` actually according to the docs I can see for wget) that will only effect the wget program. CMake's ExternalProject_Add [uses libcurl](https://cmake.org/pipermail/cmake/2015-October/061850.html) under the hood you you will need to set the proxy settings for curl not wget. Curl uses the standard environment variables `http_proxy` and `https_proxy`: See [here](https://stackoverflow.com/questions/9445489/performing-http-requests-with-curl-using-proxy) for how to set them. --- [Visit Topic](https://discourse.ros.org/t/ament-build-with-proxy-setup/2913/4) or reply to this email to respond.
