# ECMConfiguredInstall
# --------------------
#
# Takes a list of files, runs configure_file on each and installs the resultant configured files in the given location.
#
# Any suffix of ".in" in the passed file names wil be stripped from the file name at the installed location.
#
# ::
#
#   ecm_install_configured_files(
#       INPUT <file> [<file2> [...]]
#       DESTINATION <INSTALL_DIRECTORY>
#       [COPYONLY]
#       [ESCAPE_QUOTES]
#       [@ONLY]
#       [COMPONENT <component>])
#
# Example usage:
#
# .. code-block:: cmake
#
#   ecm_install_configured_files(INPUT foo.txt.in DESTINATION ${KDE_INSTALL_DATADIR} @ONLY)
#
# This wil install the file as foo.txt with any cmake variable replacements made into the data directory.
#
# Since 5.73.0.
