---------------------
.. versionadded:: 3.8
The module defines :command:`configure_file` similar command to
configure file templates prepared in QtIFW/SDK/Creator style.
Commands
^^^^^^^^
The module defines the following commands:
.. command:: cpack_ifw_configure_file
Copy a file to another location and modify its contents.
::
cpack_ifw_configure_file(<input> <output>)
Copies an ``<input>`` file to an ``<output>`` file and substitutes variable
values referenced as ``%{VAR}`` or ``%VAR%`` in the input file content.
Each variable reference will be replaced with the current value of the
variable, or the empty string if the variable is not defined.
#]=======================================================================]
# NOTE: This file used to himself packaging via CPack IFW generator and
# should be compatible with minimal CMake version defined in
# ../CMakeLists.txt file.
