try_compile: Don't accept try_run arguments
Modify cmCoreTryCompile
to only recognize try_run
arguments when actually parsing try_run
. (The old behavior was to recognize try_run
arguments for try_compile
also and then complain.)
This has a small chance that a try_run
keyword will be consumed as part of a multi-valued keyword argument. However, this behavior is more consistent with other commands, as we don't normally treat keywords as universally reserved. Also, the code is noticeably simplified.
