# This file provides the functions ecm_add_test() and ecm_add_tests().
#
# ecm_add_test(<sources> TEST_NAME <name> NAME_PREFIX <prefix> LINK_LIBRARIES <libraries/targets> [GUI])
#
# Add a new unit test using the passed source files. The parameter TEST_NAME is used to set the name
# of the resulting test. It may be omitted if there is exactly one source file. In that case the name of
# the source file (without the file extension) will be used as the test name.
# If the flag GUI is passed the test binary will be a GUI executable, otherwise the resulting
# binary will be a console application.
#
# ecm_add_tests(<sources> NAME_PREFIX <prefix> LINK_LIBRARIES <libraries/targets> [GUI])
#
# Add a new unit test for every source file passed. The name of the tests will be the name of the
# corresponding source file minus the file extension. If NAME_PREFIX is set, that string will be
# prepended to each of the unit test names. Each of the unit tests will be linked against the
# libraries and/or targets passed in the LINK_LIBRARIES parameter.
# If the flag GUI is passed the test binary will be a GUI executable, otherwise the resulting
# binary will be a console application.
