 We use [cmake](https://cmake.org) as build tool.

-### Troubleshooting
-
-#### protobufConfig.cmake not found
-
-If you encounter something like `protobufConfig.cmake not found` when doing
-`cmake -B . ..` your system doesn't have the gRPC library installed at all
-or your installation doesn't have the required `protobufConfig.cmake`
-file. In this case you can install grpcc manually by cloning the
-repository and its submodules nad building it from the sources:
-
-```sh
-RUN git clone --recurse-submodules -b v1.38.1 https://github.com/grpc/grpc
-cd grpc
-mkdir -p cmake/build
-cp cmake/build
-cmake -DgRPC_INSTALL=ON \
-      -DgRPC_BUILD_CSHARP_EXT=OFF \
-      -DgRPC_BUILD_GRPC_CSHARP_PLUGIN=OFF \
-      -DgRPC_BUILD_GRPC_PYTHON_PLUGIN=OFF \
-      -DgRPC_BUILD_GRPC_RUBY_PLUGIN=OFF \
-      -DgRPC_BUILD_GRPC_PHP_PLUGIN=OFF \
-      -DgRPC_BUILD_GRPC_OBJECTIVE_C_PLUGIN=OFF \
-      -DgRPC_BUILD_GRPC_NODE_PLUGIN=OFF \
-      -DgRPC_BUILD_TESTS=OFF \
-      ../..
-make -j3  # Or whatever number of jobs suits your system
-make install
-```
-
-It may make sense to specify a custom directory for your grpc
-installation such as `$HOME/.local` by adding
-`-DCMAKE_INSTALL_PREFIX=/path/to/install/dir` to the above `cmake`
-command. This prevents interference with a possible system-wide
-installation of grpc that's lacking the relevant cmake files.
-
-Depending on your system, it may be necessary to manually install the
-`abseil` submodule:
-
-```sh
-cd grpc
-mkdir -p third_party/abseil-cpp/cmake/build
-cd third_party/abseil-cpp/cmake/build
-cmake -DCMAKE_POSITION_INDEPENDENT_CODE=TRUE ../..
-make -j3
-make install
-```
-
-As above, it may make sense to specify a `CMAKE_INSTALL_PREFIX` in
-order to not interfere with system-wide installations.
-
-You may have to repeat this for other submodules that haven't been
-installed correctly by `make install` of `grpc`.

 ### Run
 
 In the build directory, run `ctest`
 
-### Troubleshooting
-
-Depending on your gtest installation, there may be warnings treated as
-errors during the above build command, e.g., a
-`-Werror=maybe-uninitialized` in
-`caosdb-cpplib-new/build/_deps/googletest-src/googletest/src/gtest-death-test.cc`. In
-that case, suppress the corresponding warning by adding
-`-DCMAKE_CXX_FLAGS="-Wno-maybe-uninitialized"` to the cmake command in 2.
-
 ### Framework
 
 We use [GoogleTest](https://google.github.io/googletest/) for unit testing.
