# Defines a function to install the symbols for a target
#
# install_debug_symbols(TARGETS <target_name> [...] [DESTINATION <dest>]
# [CONFIGURATIONS <configname> [...]] [PASSTHRU <arg to pass to INSTALL> [...]])
#
# DESTINATION is only optional if CMAKE_INSTALL_BINDIR and CMAKE_INSTALL_LIBDIR are set,
# then it will use CMAKE_INSTALL_BINDIR for executables (and DLLs) and CMAKE_INSTALL_LIBDIR
# for libraries (static libraries only on DLL platforms).
#
# CONFIGURATIONS are the config names for which symbols (PDB files) are expected -
# the default of RelWithDebInfo Debug is correct unless you've dramatically changed
# the set of configs.
#
# Anything after PASSTHRU is passed directly to the install( command after the arguments
# that the function generates.
#
# Currently a no-op if using CMake pre-3.2 (can't use generator expressions before then
# to get symbol location) or if not using MSVC (MSVC keeps its symbols separate in PDB files
# necessitating this function in the first place).
