# Generate a qt_lib_XXX.pri file.
#
# This file is to be used in CMake script mode with the following variables set:
# IN_FILES: path to the qt_lib_XXX.cmake files
# OUT_FILE: path to the generated qt_lib_XXX.pri file
# CONFIGS: the configurations Qt is being built with
# LIBRARY_SUFFIXES: list of known library extensions, e.g. .so;.a on Linux
# LIBRARY_PREFIXES: list of known library prefies, e.g. the "lib" in "libz" on on Linux
# LINK_LIBRARY_FLAG: flag used to link a shared library to an executable, e.g. -l on UNIX
# IMPLICIT_LINK_DIRECTORIES: list of implicit linker search paths
#
# QMAKE_LIBS_XXX values are split into QMAKE_LIBS_XXX_DEBUG and QMAKE_LIBS_XXX_RELEASE if
# debug_and_release was detected. The CMake configuration "Debug" is considered for the _DEBUG
# values. The first config that is not "Debug" is treated as _RELEASE.
#
# The library values are transformed from an absolute path into link flags
# aka from "/usr/lib/x86_64-linux-gnu/libcups.so" to "-lcups".
