Pull request overview
This PR adds a CMake option SRAL_DISABLE_UIA to conditionally exclude UI Automation (UIA) support from the SRAL library, addressing static linking conflicts that can occur with UIA in some projects.
Key Changes:
- Adds
SRAL_DISABLE_UIACMake option (default OFF) to control UIA compilation - Conditionally compiles UIA-related source files and links uiautomationcore.lib
- Changes default MSVC runtime library from static to dynamic linking

When SRAL_NO_UIA is defined, the condition still checks for SRAL_ENGINE_UIA even though the UIA engine is never initialized. This comparison against SRAL_ENGINE_UIA will never be true when UIA is disabled, but the check itself can still execute. Consider wrapping the SRAL_ENGINE_UIA check in the condition with a preprocessor directive to avoid the unnecessary comparison when UIA is disabled.

This change modifies the default runtime library from static (MultiThreaded) to dynamic (MultiThreadedDLL), which is unrelated to the UIA feature toggle. This is a breaking change that could affect existing users who depend on static linking and should be documented or split into a separate PR. If this change is intentional and related to UIA compatibility issues, it should be explained in the PR description.

Add SRAL_DISABLE_UIA option (default OFF) to conditionally compile UIA
Sometimes uia conflicts with static linking sral in some projects.
