# InstalledTests.cmake
#
# Adds option ENABLE_INSTALLED_TESTS and helper macros to manage
# installed test. There are also set variables:
# INSTALLED_TESTS_EXEC_DIR - where to store installed tests and eventually its data
# INSTALLED_TESTS_META_DIR - where to store .test meta files for installed tests
#
# install_test_if_enabled(_test_target _type _environ)
#    Adds rules to install a test whose target is _test_target (the one
#    used for add_executable()), while the target name should match
#    the executable name. The _type and _environ are used for populating
#    the .test meta file.
#
# install_behave_tests_if_enabled(_testsvar _type _environ)
#    Adds rules to install the 'behave' tests as stored in _testsvar
#    in the current source directory.
