gRPC C++ - Building from source

[Claus Volko]

I am using Windows 10.

When I am following the steps described at https://github.com/grpc/grpc/blob/master/BUILDING.md#build-from-source and execute the code in https://github.com/grpc/grpc/blob/master/test/distrib/cpp/run_distrib_test_cmake.sh, I run into a problem related to absl.

When I execute this code:

mkdir "cmake/build"
cd "cmake/build"
cmake -DCMAKE_BUILD_TYPE=Release -DgRPC_INSTALL=ON -DgRPC_BUILD_TESTS=OFF -DgRPC_CARES_PROVIDER=package -DgRPC_ABSL_PROVIDER=package -DgRPC_PROTOBUF_PROVIDER=package -DgRPC_RE2_PROVIDER=package -DgRPC_SSL_PROVIDER=package -DgRPC_ZLIB_PROVIDER=package ../..
cmake --build .

I get the following error message:

<<

-- Selecting Windows SDK version 10.0.22621.0 to target Windows 10.0.19045.
CMake Error at cmake/abseil-cpp.cmake:38 (find_package):
  Could not find a package configuration file provided by "absl" with any of
  the following names:

    abslConfig.cmake
    absl-config.cmake

  Add the installation prefix of "absl" to CMAKE_PREFIX_PATH or set
  "absl_DIR" to a directory containing one of the above files.  If "absl"
  provides a separate development package or SDK, be sure it has been
  installed.
Call Stack (most recent call first):
  CMakeLists.txt:335 (include)


-- Configuring incomplete, errors occurred!

What can I do about that?

Best Regards

I solved the problem by using this command:

cmake -DCMAKE_BUILD_TYPE=Release -DgRPC_INSTALL=ON -DgRPC_BUILD_TESTS=OFF -DgRPC_CARES_PROVIDER=module -DgRPC_ABSL_PROVIDER=module -DgRPC_PROTOBUF_PROVIDER=module -DgRPC_RE2_PROVIDER=module -DgRPC_SSL_PROVIDER=module -DgRPC_ZLIB_PROVIDER=module ../..

However, now I have the problem that when I try to build the example program "helloworld" for cpp, libraries related to OpenSSL are missing. I installed OpenSSL on my machine and the package does not contain a file named SSL.lib, it only contains a file named libssl.lib. The same goes for crypto.lib. Where can I get these files?

Meanwhile I've resolved all problems on my own and successfully built the "helloworld" example program for C++. So there is no need to reply to my inquiries.

I temporarily removed the references to the libraries related to OpenSSL from the .vcxproj files. Now I get this error:
