Building Iroha in Docker with cmake

Question

I try to build Iroha Hyperledger using Doker. after I clone the image and try to execute the build with CMake

cmake -H. -Bbuild -DCMAKE_TOOLCHAIN_FILE=/opt/dependencies/scripts/buildsystems/vcpkg.cmake -G "Ninja"

I got this error:

Could not find toolchain file:
  /opt/dependencies/scripts/buildsystems/vcpkg.cmake
Call Stack (most recent call first):
  CMakeLists.txt:12 (PROJECT)

I use CMake 3.16

Any help

Answer 1

Commands to do (as @kyb said) and according to instruction:

1. Installing dependencies:

apt-get update; \
apt-get -y --no-install-recommends install \
build-essential ninja-build \
git ca-certificates tar curl unzip cmake

2. Clonning iroha:

git clone https://github.com/hyperledger/iroha.git

3. Building dependencies:

iroha/vcpkg/build_iroha_deps.sh
vcpkg/vcpkg integrate install

As a result You will see command like:

-DCMAKE_TOOLCHAIN_FILE=/path/to/vcpkg/scripts/buildsystems/vcpkg.cmake

4. Finally You need to add the command to the CMake command (as You provided):

cmake -H. -Bbuild -DCMAKE_TOOLCHAIN_FILE=/opt/dependencies/scripts/buildsystems/vcpkg.cmake -G "Ninja"

5. Last step would be run ninja:

cmake --build . --target irohad -- -j<number of threads>

6. Optionally You can install the binaries:

cmake --install . --target irohad
