zeek/cmake/InstallPackageConfigFile.cmake
Jon Siwek dec97ab56d Changes to the way user-modifiable config files are installed.
- Duplicates of the distribution's configuration files are now always
  installed with a .example suffix
- Added --binary-package configure option to toggle configure logic
  specific to the creation of binary packages.
- When not in binary packaging mode, `make install` never overwrites
  existing configure files in case they've been modified.  The previous
  behavior (CMake's default) would only avoid overwriting modified files
  if one consistently uses the same build directory and doesn't reconfigure.
- Fixed an issue with Mac package's pre-install script not preserving ACLs
- Minor cleanup/refactor of the make-mac/rpm-packages scripts

# This macro can be used to install configuration files which
# users are expected to modify after installation. It will:
#
# - Always install one version of the file with a .example suffix
# - 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.
