# - Use file for Geant4
|
|
# This file may be included after a find_package call has successfully
|
|
# located Geant4 to set global compile definitions, include directories,
|
|
# and compiler flags for building and linking to the Geant4 libraries.
|
|
#
|
|
# If Geant4 has been located via the Geant4Config.cmake config file, the
|
|
# following variable will be set:
|
|
#
|
|
# Geant4_USE_FILE : Point to the location of the use file for the found
|
|
# Geant4 installation.
|
|
#
|
|
# Inclusion of this file, e.g. via
|
|
#
|
|
# include(${Geant4_USE_FILE})
|
|
#
|
|
# results in the addition of the Geant4 compile definitions and
|
|
# include directories to those of the directory in which this file is
|
|
# included.
|
|
#
|
|
# Header paths are added via include_directories as SYSTEM type directories
|
|
#
|
|
# The recommended Geant4 compiler flags are also prepended to
|
|
# CMAKE_CXX_FLAGS but duplicated flags are NOT removed. This permits
|
|
# client of UseGeant4 to override Geant4's recommended flags if required
|
|
# and at their own risk.
|
|
#
|
|
# Advanced users requiring special sets of flags, or the removal of
|
|
# duplicate flags should therefore *not* use this file, preferring the
|
|
# direct use of the Geant4_XXXX variables set by the Geant4Config file.
|
|
#
|
|
# The last thing the module does is to optionally include an internal Use
|
|
# file. This file can contain variables, functions and macros for strict
|
|
# internal use in Geant4, such as building and running validation tests.
