try_compile: Add test for bad call error cases Add a RunCMake.try_compile test to cover cases of bad invocation of the try_compile command.

include(RunCMake)
try_compile: Add COPY_FILE_ERROR option to capture failure When the COPY_FILE operation fails optionally capture the error message with a COPY_FILE_ERROR option instead of reporting the error immediately. This gives callers a chance to do something else or report the error. Teach the RunCMake.try_compile test to cover bad argument combinations involving COPY_FILE_ERROR. Teach the TryCompile test to cover the case of a COPY_FILE error message captured by COPY_FILE_ERROR.

try_compile: Refactor argument processing Process all arguments in a single loop using a simple state machine. While at it, fix some error message typos. Also allow LINK_LIBRARIES with no actual libraries to disable use of the -DLINK_LIBRARIES=... from the CMAKE_FLAGS. This was already possible in the old logic if LINK_LIBRARIES was immediately followed by another keyword argument instead of the end of the argument list, so allow it in general. Update the RunCMake.try_compile test cases accordingly.

try_compile: Add signature to allow multiple SOURCES Extend the signature try_compile(RESULT_VAR <bindir> <srcfile> ...) to allow multiple sources as try_compile(RESULT_VAR <bindir> SOURCES <srcfile>... ...) Process the sources to generate a CMakeLists.txt that enables all needed languages. Teach the TryCompile test to try cases with two sources of the same language and of mixed languages. Teach RunCMake.try_compile to cover error cases for the signature.

try_compile: Pass linker flags into test project (#14066) Copy CMAKE_EXE_LINKER_FLAGS into the test project generated by try_compile, just like we already copy CMAKE_<LANG>_FLAGS. Add CMake Policy CMP0056 to activate this behavior in a compatible way, but do not warn by default when the policy is not set since it will affect all try_compile calls. Extend the RunCMake.try_compile test with a case covering this behavior for each policy setting.

try_compile: Optionally forward custom platform variables to test project Add a `CMAKE_TRY_COMPILE_PLATFORM_VARIABLES` variable to specify a list of custom variables to be forwarded to a `try_compile` test project. This will be useful for platform information modules or toolchain files to forward some platform-specific set of variables from the host project (perhaps set in its cache) to the test project so that it can build the same way.

try_compile: Add option to control type of target Create a `CMAKE_TRY_COMPILE_TARGET_TYPE` option to specify use of `add_library(... STATIC ...)` for the generated test project. This will be useful for cross-compiling toolchains that cannot link a binary without custom flags or scripts.

try_compile: Test that CMake re-runs on input change With the Makefile and Ninja generators we expect that touching the input source file for a try_compile will cause CMake to re-run on the next build. Extend the RunCMake.try_compile test with a case covering this. Also check that CMake does not re-run if nothing has changed.
