In order to add external library dependencies (which should provide a cmake package definition) the following lines have to be added to the file CMakeLists.txt:

	FIND_PACKAGE(<library> REQUIRED <components>)
	GET_PROPERTY(<library>_INCLUDE_DIRS DIRECTORY PROPERTY INCLUDE_DIRECTORIES)
	LIST(APPEND USER_INCLUDES ${<library>_INCLUDE_DIRS})
	LIST(APPEND USER_LIBS ${<library>_LIBS})

If, for example, the libraries mrpt-base and mrpt-gui should be added, the following lines have to be used:

	FIND_PACKAGE(MRPT REQUIRED base gui)
	GET_PROPERTY(MRPT_INCLUDE_DIRS DIRECTORY PROPERTY INCLUDE_DIRECTORIES)
	LIST(APPEND USER_INCLUDES ${MRPT_INCLUDE_DIRS})
	LIST(APPEND USER_LIBS ${MRPT_LIBS})
					

For further information on how to create cmake package-definitions for external libraries see: https://cmake.org/Wiki/CMake:How_To_Find_Libraries

System libraries (e.g. installed in /usr/lib) can be added as follows:

	LIST(APPEND USER_LIBS "<library>")

The library libbluetooth, for example, can be added as follows:

	LIST(APPEND USER_LIBS "bluetooth")
					

Additional compiler flags can be added to the CMakeLists.txt as follows:

	SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -<compiler flag>")

For instance, in order to add the compiler flag "ENABLE_HASH" use this line:

	SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -DENABLE_HASH")
					

All user source files inside of the src/ folder that have the ending .cc or .hh will be automatically included into the build process of the component. In order to use a custom subfolder inside of the src/ folder add the following lines to the CMakeLists.txt file:

	FILE(GLOB SRCS src/<directory>/*.cc)
	LIST(APPEND USER_SRCS ${SRCS})
	LIST(APPEND USER_INCLUDES src/<directory>/)

An example can be found in the SmartVisualization component. The following lines were used to add the source files of the directory "visualization":

	FILE(GLOB SRCS src/visualization/*.cc)
	LIST(APPEND USER_SRCS ${SRCS})
	LIST(APPEND USER_INCLUDES src/visualization/)
					

In case the subdirectory contains an own cmake project, use the following approach instead:

	ADD_SUBDIRECTORY(<path>)
	LIST(APPEND USER_INCLUDES <path>)
	LIST(APPEND USER_LIBS <libraries>)

An example is shown in the component SmartXsensIMUMTiServer:

	ADD_SUBDIRECTORY(${PROJECT_SOURCE_DIR}/src/xsensSDK)
	LIST(APPEND USER_INCLUDES ${PROJECT_SOURCE_DIR}/src/xsensSDK/Software_Development/CMTsrc)
	LIST(APPEND USER_LIBS XSense)
					

Here is an example cmake project (for the XSense SDK):

	SmartXsensIMUMTiServer/src/xsensSDK/CMakeLists.txt:

	PROJECT(XSense)

	FILE(GLOB SRCS ${PROJECT_SOURCE_DIR}/Software_Development/CMTsrc/*.cpp)
	FILE(GLOB HDRS ${PROJECT_SOURCE_DIR}/Software_Development/CMTsrc/*.h)

	INCLUDE_DIRECTORIES(${PROJECT_SOURCE_DIR}/Software_Development/CMTsrc)

	ADD_LIBRARY(${PROJECT_NAME} STATIC ${SRCS} ${HDRS})
