It might be necessary to set the \parameter{CMAKE_CXX_STANDARD} according to the settings used to build the framework.

All dependencies of the framework such as ROOT or Boost.Random are automatically added as CMake targets and can be used by the module.

The required \parameter{CMAKE_CXX_STANDARD} is automatically inferred from the settings used to build the framework.

Additional libraries can be linked to the module using the standard CMake command

\begin{minted}[frame=single,framesep=3pt,breaklines=true,tabsize=2,linenos]{cmake}

TARGET_LINK_LIBRARIES(${MODULE_NAME} MyExternalLibrary)

    DESTINATION include

    PATTERN "*.hpp"

    PATTERN "*.h"

    PATTERN "objects.h" EXCLUDE

    PATTERN "Linkdef.h" EXCLUDE)
