# Checks if the test project can be built successfully. Arguments:
#
# NO_CLEAN_STEP: Skips calling 'clean' target before building.
#
# NO_BUILD_PROJECT_ARG: Skips adding --build-project argument. Useful when using Xcode generator.
#
# GENERATOR: Use a custom generator. When not specified, uses existing CMAKE_GENERATOR value.
#
# NO_IOS_DEFAULT_ARGS: Skips setting default iOS-specific options like the generator to be used.
#
# MAKE_PROGRAM: Specify a different make program. Can be useful with a custom make or ninja wrapper.
#
# BUILD_TYPE: Specify a different CMake build type. Defaults to CMAKE_BUILD_TYPE if it is not empty.
#             Which means no build type is passed if the top-level project is configured with a
#             multi-config generator.
#
# SIMULATE_IN_SOURCE: If the option is specified, the function copies sources of the tests to the
#                     CMAKE_CURRENT_BINARY_DIR directory, creates internal build directory in the
#                     copied sources and uses this directory to build and test the project.
#                     This makes possible to have relative paths to the source files in the
#                     generated ninja rules.
#
# BUILD_DIR: A custom build dir relative to the calling project CMAKE_CURRENT_BINARY_DIR.
#            Useful when configuring the same test project with different options in separate
#            build dirs.
#
# BINARY: Path to the test artifact that will be executed after the build is complete. If a
#         relative path is specified, it will be counted from the build directory.
#         Can also be passed a random executable to be found in PATH, like 'ctest'.
#
# BINARY_ARGS: Additional arguments to pass to the BINARY.
#
# TESTNAME: a custom test name to use instead of the one derived from the source directory name
#
# BUILD_OPTIONS: a list of -D style CMake definitions to pass to ctest's --build-options (which
#                are ultimately passed to the CMake invocation of the test project). You may
#                escape semicolons inside the definitions using:
#                https://cmake.org/cmake/help/latest/manual/cmake-language.7.html#bracket-argument
#                so the argument containing list will look as following:
#                    -DLIST_ARGUMENT=item1[[;]]item2[[;]]...itemN.
