[![AUR license](https://img.shields.io/aur/license/lmdbal?style=flat-square)](https://git.macaw.me/blue/lmdbal/raw/branch/master/LICENSE.md)

### Prerequisites

- Qt 5 or higher
- lmdb
- CMake 3.16 or higher
- Doxygen (optional, for documentation)

### Using with CMake

#### As a system library

If you're using LMDBAL as a system library you probably have no control over it's build options. The easiest way to include the project is to add following

```
find_package(lmdbal)
if (LMDBAL_FOUND)
    target_include_directories(yourTarget PRIVATE {LMDBAL_INCLUDE_DIRS})
    target_link_libraries(yourTarget PRIVATE LMDBAL::LMDBAL)
endif()
```

#### As an embeded subproject
//TODO

### Building

LMDBAL uses CMake as a build system.

Please check the prerequisites and install them before building.

Here is an easy way to build a project

```
$ git clone https://git.macaw.me/blue/lmdbal
$ cd lmdbal
$ mkdir build
$ cd build
$ cmake .. [ *optional keys* ]
$ cmake --build .
$ cmake --install . --prefix install
```

This way will create you a `lmdbal/build` directory with temporary files, and `lmdbal/build/install` with all the export files for installation to the system.

After `cmake ..` you can specify keys to alter the building process. In this context building keys are transfered like so

```
cmake .. -D KEY1=VALUE1 -D KEY2=VALUE2 ...
```

#### List of keys

Here is the list of keys you can pass to configuration phase of `cmake ..`:

- `CMAKE_BUILD_TYPE` - `Debug` just builds showing all warnings, `Release` builds with no warnings and applies optimizations (default is `Debug`);
- `BUILD_STATIC` - `True` builds project as a static library, `False` builds as dynamic (default is `False`);
- `BUILD_TESTS` - `True` build unit tests, `False` does not (default is `False`);
- `BUILD_DOC` - `True` build doxygen documentation, `False` does not (default is `False`);
- `QT_VERSION_MAJOR` - `5` links against Qt5, `6` links agains Qt6, there is no default, so, if you didn't specify it the project will chose automatically;

#### Running tests

If you built the library with `-D BUILD_TESTS=True`, then there will be `lmdbal/build/tests/runUnitTests` executable file. You can simply run it as

```
./runUnitTests
```

if you're in the same directory with it
