# ECMAddTests
# -----------
#
# Convenience functions for adding tests.
#
# ::
#
# ecm_add_tests(<sources> LINK_LIBRARIES <library> [<library> [...]]
# [NAME_PREFIX <prefix>]
# [GUI])
#
# A convenience function for adding multiple tests, each consisting of a
# single source file. For each file in <sources>, an executable target will be
# created (the name of which will be the basename of the source file). This
# will be linked against the libraries given with LINK_LIBRARIES. Each
# executable will be added as a test with the same name.
#
# If NAME_PREFIX is given, this prefix will be prepended to the test names, but
# not the target names. As a result, it will not prevent clashes between tests
# with the same name in different parts of the project, but it can be used to
# give an indication of where to look for a failing test.
#
# If the flag GUI is passed the test binaries will be GUI executables, otherwise
# the resulting binaries will be console applications (regardless of the value
# of CMAKE_WIN32_EXECUTABLE or CMAKE_MACOSX_BUNDLE). Be aware that this changes
# the executable entry point on Windows (although some frameworks, such as Qt,
# abstract this difference away).
#
# The generated target executables will have the effects of ecm_mark_as_test()
# (from the :module:`ECMMarkAsTest` module) applied to it.
#
# ::
#
# ecm_add_test(<sources> LINK_LIBRARIES <library> [<library> [...]]
# [TEST_NAME <name>]
# [NAME_PREFIX <prefix>]
# [GUI])
#
# This is a single-test form of ecm_add_tests that allows multiple source files
# to be used for a single test. If using multiple source files, TEST_NAME must
# be given; this will be used for both the target and test names (and, as with
# ecm_add_tests(), the NAME_PREFIX argument will be prepended to the test name).
#
#
# Since pre-1.0.0.
