C++ implementation of TUF OTA update client based on aktualizr

List of aktualizr-lite dependencies can be found here or in the Dockerfile that defines a docker container which includes the all dependencies required for aktualizr-lite building and unit testing.

git clone --recursive https://github.com/foundriesio/aktualizr-lite
cd aktualizr-lite

or if you cloned the repo without --recursive flag

git submodule update --init --recursive

Run make to build and/or apply clang-format or clang-tidy utilities. Use the environment variables to amend the make commands behavior.

[<MAKE ENV VARS>] make [-f dev-flow.mk] <config | build | format | tidy >

The make environment variables are:

• BUILD_DIR - a build directory, ./build by default;
• CCACHE_DIR - a ccache directory, ./ccache by default;
• TARGET - a target to build, aklite-test by default. Could be aktualizr-lite if no need to build tests;
• CXX - a compiler to use, clang++ or the compiler specified in a host's env by default.

If -f dev-flow.mk is specified then the make command is executed on a host, otherwise - in the foundries/aklite-dev container. A user can specify their own container to run the commands in by overriding CONTAINER environment variable.

[<MAKE ENV VARS>] make [-f dev-flow.mk] test

The make environment variables are:

• TEST_LABEL - a label (regexp) of the target tests. For example, aklite:compose-apps, by default, is set to aklite - run all aktualizr-lite tests;
• CTEST_ARGS - additional ctest parameters, by default is set to --output-on-failure.
• GTEST_FILTER - a regexp to filter tests within gtest suits, e.g. GTEST_FILTER="*OstreeUpdateNoSpaceRetry*" TEST_LABEL="aklite:liteclient" make.
