Matt McCormick e2b1f0583f try_run: Add support for LINK_LIBRARIES option.
Most functionality is already implemented in Source/cmCoreTryCompile.{h,cxx}.
Document and improve argument parsing.

This functionality is already being used by a number of modules, like
CheckCSourceCompiles.cmake, but it is not documented.

Brad King 88eb5824da 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.

Brad King d05a9bd1e6 Cygwin: Avoid legacy warnings in RunCMake.* tests
Set the minimum required version of CMake high enough to avoid the
warning for CMAKE_LEGACY_CYGWIN_WIN32.  The warning appears on stderr
and breaks the expected output matching.

Brad King c28715b16c 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.

Brad King 482f1122ad 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.

Brad King d06db7ebe8 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.

Brad King b680824a5f 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.
