CHANGE TO CORRECT REPO:

influxdblpexporter

There are multiple ways to add this library to your project. There are too many tools for C++ to describe them all.

I will describe two methods, both for CMake users.

The first method will download the source code and build against it, the second will use a system installed version of the library.

The first method works best in CI/CD pipelines without to much hassle. This is therefore the preferred method.

This method emulates dependency management of more modern languages and build systems like Rust+Cargo and Go as best as it can.

Consider the following example project:

cmake_minimum_required(VERSION 3.17)
project(example)

add_executable(${PROJECT_NAME} main.cpp)
target_compile_features(${PROJECT_NAME} PUBLIC cxx_std_17)

This will build a C++17 project with a main.cpp file.

Now to add this library to the project you can use the FetchContent CMake module.

The minimal requirement is to add:

include(FetchContent)
FetchContent_Declare(
        influxdblpexporter
        GIT_REPOSITORY https://github.com/crosscode-nl/influxdblpexporter
        GIT_TAG main
)
FetchContent_MakeAvailable(influxdblpexporter)
target_link_libraries(${PROJECT_NAME} influxdblpexporter)

This will result in the following CMakeLists.txt:

cmake_minimum_required(VERSION 3.17)
project(example)

add_executable(${PROJECT_NAME} main.cpp)
target_compile_features(${PROJECT_NAME} PUBLIC cxx_std_17)

include(FetchContent)
FetchContent_Declare(
        influxdblpexporter
        GIT_REPOSITORY https://github.com/crosscode-nl/influxdblpexporter
        GIT_TAG main
)
FetchContent_MakeAvailable(influxdblpexporter)
target_link_libraries(${PROJECT_NAME} influxdblpexporter)

You can also put the first block in a cmake/influxdblpexporter.cmake file and include it as following:

cmake_minimum_required(VERSION 3.17)
project(example)

add_executable(${PROJECT_NAME} main.cpp)
target_compile_features(${PROJECT_NAME} PUBLIC cxx_std_17)

include(cmake/influxdblpexporter.cmake)

Now see the examples to learn how to use this library.

TIP: Use GIT_TAG in FetchContent_Declare to pin a certain version to get reproducible builds.

This method will use CMake's find_package.

The first step is to install the library on the system.

This method requires influxdblpexporter to be build and installed on the system.

git clone https://github.com/crosscode-nl/influxdblpexporter
mkdir influxdblpexporter-build
cd influxdblpexporter-build
cmake ../influxdblpexporter -DCMAKE_BUILD_TYPE=Release
sudo make install 

Or if you want to install it somewhere in you home directory, for example:

git clone https://github.com/crosscode-nl/influxdblpexporter
mkdir influxdblpexporter-build
cd influxdblpexporter-build
cmake ../influxdblpexporter -DCMAKE_BUILD_TYPE=Release -DCMAKE_INSTALL_PREFIX=/home/developer/libraries
make install 

Consider the following example project:

cmake_minimum_required(VERSION 3.17)
project(example)

add_executable(${PROJECT_NAME} main.cpp)
target_compile_features(${PROJECT_NAME} PUBLIC cxx_std_17)

To use an installed library you just have to add:

find_package(InfluxDBLPExporter 1.0.0 REQUIRED)
target_link_libraries(${PROJECT_NAME} InfluxDBLPExporter::influxdblpexporter)

This will result in the following CMakeLists.txt:

cmake_minimum_required(VERSION 3.17)
project(example)

add_executable(${PROJECT_NAME} main.cpp)
target_compile_features(${PROJECT_NAME} PUBLIC cxx_std_17)

find_package(InfluxDBLPExporter 1.0.0 REQUIRED)
target_link_libraries(${PROJECT_NAME} InfluxDBLPExporter::influxdblpexporter)

When you installed the library in a different location then you have to add -DCMAKE_PREFIX_PATH=/home/developer/libraries to your CMake command.
