# This macro can be used to install configuration files which
# users are expected to modify after installation. It will:
#
# - If binary packaging is enabled:
# Install the file in the typical CMake fashion, but append to the
# INSTALLED_CONFIG_FILES cache variable for use with the Mac package's
# pre/post install scripts
# - If binary packaging is not enabled:
# Install the script in a way such that it will check at `make install`
# time whether the file does not exist. See InstallClobberImmune.cmake
#
# _srcfile: the absolute path to the file to install
# _dstdir: absolute path to the directory in which to install the file
# _dstfilename: how to (re)name the file inside _dstdir

# If packaging mode is enabled, always install the distribution's
# version of the file. The Mac package's pre/post install scripts
# or native functionality of RPMs will take care of not clobbering it.

# handling of configuration file conflicts so install an example file
