Hello!
I am trying to build the v1.18.0 helloworld example (superbuild
<https://github.com/grpc/grpc/blob/master/examples/cpp/helloworld/cmake_externalproject/CMakeLists.txt>version)
using VS2017 at Windows10.
Build fails with message "Could NOT find OpenSSL, try to set the path to
OpenSSL root folder in the system variable OPENSSL_ROOT_DIR", full
traceback is in the .txt.
I have tried to set OPENSSL_ROOT_DIR to "grpc/third_party/boringssl" or
"grpc/third_party/boringssl/include", but this haven't helped.
Using this guide <https://github.com/grpc/grpc/blob/master/BUILDING.md> I
have managed to build grpc itself (with warning 'gRPC_INSTALL will be
forced to FALSE because gRPC_ZLIB_PROVIDER is "module"', but no errors). I
used "Visual Studio 15" generator, not Ninja (not sure if it matters). But
I think it means that all necessary dependencies are actually available,
just not found by cmake.
Any hints how can this example be build (perhaps not with boringssl) would
be very helpful!
