I tried again (Ubuntu 18.04):
* binaries verification succeeded
* source verification failed in gRPC configure step:
CMake Error at cmake/cares.cmake:38 (find_package):
Could not find a package configuration file provided by "c-ares" with any
of the following names:
c-aresConfig.cmake
c-ares-config.cmake
Add the installation prefix of "c-ares" to CMAKE_PREFIX_PATH or set
"c-ares_DIR" to a directory containing one of the above files. If "c-ares"
provides a separate development package or SDK, be sure it has been
installed.
Call Stack (most recent call first):
CMakeLists.txt:139 (include)
Problem is, Ubuntu's c-ares does not provide any CMake files:
$ dpkg -L libc-ares-dev
