# Usage:
#
# ngspice uses pkg-config to gather the configuration information so the pkg-config
# information is used to populate the CMake find_* commands. When pkg-config is not
# available, the fallback is the default platform search paths set up by CMake. The
# default search paths can be overridden by user. The order of precedence is as
# follows:
#
# User defined root path NGSPICE_ROOT_DIR on CMake command line.
# User defined root path environment variable NGSPICE_ROOT_DIR.
# Paths generated by pkg-config.
# The default system paths configured by CMake
#
# For a specific ngspice include path not defined above set NGSPICE_INCLUDE_PATH.
#
# For a specific ngspice library path not defined above set NGSPICE_LIBRARY_PATH.
# Use pkg-config if it's available.
