### Integrate Log4Qt Shared into CMake Project

Source: https://github.com/smokku/log4qt/blob/master/Readme.txt

Add this to your CMakeLists.txt to find, include, and link the Log4Qt shared library. Ensure Log4Qt is installed and discoverable by CMake.

```cmake
find_package(log4qt REQUIRED HINTS "${QT_MKSPECS_DIR}/cmake/Log4Qt" NO_DEFAULT_PATHS)
include_directories(${LOG4QT_INCLUDE_DIRS})
target_link_libraries(main ${QT_LIBRARIES} log4qt)
```

--------------------------------

### Build Log4Qt Static on *NIX

Source: https://github.com/smokku/log4qt/blob/master/Readme.txt

Use this command to build Log4Qt in static mode on *NIX systems. Ensure QT_USE_QTSQL and QT_USE_QTNETWORK are defined if SQL and network features are required.

```bash
cmake -DQT_USE_QTSQL=TRUE -DQT_USE_QTNETWORK=TRUE -DMAKE_BUILD_TYPE=Release -DLOG4QT_BUILD_STATIC=True .
make
make install
```

--------------------------------

### Build Log4Qt Static on Windows (MinGW)

Source: https://github.com/smokku/log4qt/blob/master/Readme.txt

Use this command to build Log4Qt in static mode on Windows using MinGW Makefiles. Ensure QT_USE_QTSQL and QT_USE_QTNETWORK are defined if SQL and network features are required.

```bash
cmake -DQT_USE_QTSQL=TRUE -DQT_USE_QTNETWORK=TRUE -DMAKE_BUILD_TYPE=Release -G "MinGW Makefiles" -DLOG4QT_BUILD_STATIC=True .
mingw32-make
mingw32-make install
```

### Build Log4Qt Shared on Windows (MinGW)

Source: https://github.com/smokku/log4qt/blob/master/Readme.txt

Use this command to build Log4Qt in shared mode on Windows using MinGW Makefiles. Ensure QT_USE_QTSQL and QT_USE_QTNETWORK are defined if SQL and network features are required.

```bash
cmake -DQT_USE_QTSQL=TRUE -DQT_USE_QTNETWORK=TRUE -DMAKE_BUILD_TYPE=Release -G "MinGW Makefiles" .
mingw32-make
mingw32-make install
```

--------------------------------

### Set Project Version

Source: https://github.com/smokku/log4qt/blob/master/CMakeLists.txt

Defines the major, minor, and release versions of the Log4Qt project and constructs the full version string. These variables are used for internal configuration and defining preprocessor macros.

```cmake
set(LOG4QT_VERSION_MAJOR 1)
set(LOG4QT_VERSION_MINOR 0)
set(LOG4QT_VERSION_RELEASE 0)
set(LOG4QT_VERSION "${LOG4QT_VERSION_MAJOR}.${LOG4QT_VERSION_MINOR}.${LOG4QT_VERSION_RELEASE}")
set(VERSION ${LOG4QT_VERSION})
set(SOVERSION ${LOG4QT_VERSION})
```

--------------------------------

### Add Log4Qt Library Target

Source: https://github.com/smokku/log4qt/blob/master/CMakeLists.txt

Defines the Log4Qt library target, specifying whether it's static or shared, and lists all source files, headers, and generated moc files required for the build.

```cmake
add_library(${PROJECT_NAME} ${LOG4QT_BUILD_CONFIGURATION} 
    ${LOG4QT_SOURCES}
    ${LOG4QT_Q_SOURCES}
    ${LOG4QT_MOC_SOURCES}
    ${LOG4QT_HEADERS}
    ${LOG4QT_Q_HEADERS})
```

--------------------------------

### Define Version Macros

Source: https://github.com/smokku/log4qt/blob/master/CMakeLists.txt

Defines preprocessor macros for the Log4Qt version, both as a numerical representation and a string. These are useful for compile-time checks and information.

```cmake
add_definitions(-DLOG4QT_VERSION=${LOG4QT_VERSION_MAJOR}*65536+${LOG4QT_VERSION_MINOR}*256+${LOG4QT_VERSION_RELEASE})
add_definitions(-DLOG4QT_VERSION_STR="${LOG4QT_VERSION}")
```

--------------------------------

### Set Library Build Configuration

Source: https://github.com/smokku/log4qt/blob/master/CMakeLists.txt

Determines whether to build a static or shared library based on the LOG4QT_BUILD_STATIC variable. The result is stored in LOG4QT_BUILD_CONFIGURATION.

```cmake
if (LOG4QT_BUILD_STATIC)
set(LOG4QT_BUILD_CONFIGURATION STATIC)
# BUILD SHARED LIBRARY
else (LOG4QT_BUILD_STATIC)
set(LOG4QT_BUILD_CONFIGURATION SHARED)
endif (LOG4QT_BUILD_STATIC)
```

--------------------------------

### Configure Static Build

Source: https://github.com/smokku/log4qt/blob/master/CMakeLists.txt

Ensures that the LOG4QT_BUILD_STATIC variable is defined. If not explicitly set, it defaults to FALSE, indicating a shared library build.

```cmake
if (NOT DEFINED LOG4QT_BUILD_STATIC)
	set (LOG4QT_BUILD_STATIC FALSE)
endif (NOT DEFINED LOG4QT_BUILD_STATIC)
```

--------------------------------

### Integrate Log4Qt Static into CMake Project

Source: https://github.com/smokku/log4qt/blob/master/Readme.txt

Add this to your CMakeLists.txt to include Log4Qt's source directory and link the static library. This method is suitable for static linking.

```cmake
add_subdirectory(../log4qt ${CMAKE_CURRENT_BINARY_DIR}/log4qt)
include_directories(../log4qt/src)
target_link_libraries(main ${QT_LIBRARIES} log4qt)
```

--------------------------------

### Include Qt Configuration

Source: https://github.com/smokku/log4qt/blob/master/CMakeLists.txt

Sets a CMake variable to prevent the use of the QtGUI module and then includes the Qt configuration file. This is typically used when building libraries that do not require a graphical interface.

```cmake
set(QT_DONT_USE_QTGUI TRUE)
include(${QT_USE_FILE})
```

--------------------------------

### Include Source Directory

Source: https://github.com/smokku/log4qt/blob/master/CMakeLists.txt

Adds the 'src' directory to the include path for the project. This allows header files within 'src' to be included without specifying the full path.

```cmake
include_directories(src)
```

--------------------------------

### Qt Meta-Object Compilation

Source: https://github.com/smokku/log4qt/blob/master/CMakeLists.txt

Uses CMake's Qt4 support to process C++ files that use Qt's meta-object system (e.g., with Q_OBJECT macro) and to automatically handle moc (Meta-Object Compiler) for Qt source files.

```cmake
qt4_wrap_cpp(LOG4QT_MOC_SOURCES ${LOG4QT_Q_HEADERS})
qt4_automoc(${LOG4QT_Q_SOURCES})
```

--------------------------------

### Conditional Compilation for Qt Modules

Source: https://github.com/smokku/log4qt/blob/master/CMakeLists.txt

Conditionally compiles specific appenders and layouts based on whether Qt SQL or Qt Network modules are enabled. This allows for modular inclusion of features.

```cmake
if (QT_USE_QTSQL)
	message("With QT_USE_QTSQL DatabaseAppender, DatabaseLayout compiled")
	list(APPEND LOG4QT_Q_HEADERS src/databaseappender.h src/databaselayout.h)
	list(APPEND LOG4QT_SOURCES src/databaseappender.cpp src/databaselayout.cpp)
endif (QT_USE_QTSQL)

if (QT_USE_QTNETWORK)
    message("With QT_USE_QTNETWORK TelnetAppender compiled")
    list(APPEND LOG4QT_Q_HEADERS src/telnetappender.h )
    list(APPEND LOG4QT_SOURCES src/telnetappender.cpp)
endif (QT_USE_QTNETWORK)
```
