Permit compiling on Win32 using Clang

[mdavis199]

I am using clang version 14.0.6 on Windows. The compiler options file-prefix-map is invalid for this platform.

If you could just surround the following function with if(NOT WIN32) ... endif(), it would be fantastic.

Catch2/CMake/CatchMiscFunctions.cmake

Lines 112 to 120 in 997a7d4

	# Adds flags required for reproducible build to the target
	# Currently only supports GCC and Clang
	function(add_build_reproducibility_settings target)
	# Make the build reproducible on versions of g++ and clang that supports -ffile-prefix-map
	if(("${CMAKE_CXX_COMPILER_ID}" STREQUAL "GNU" AND NOT ${CMAKE_CXX_COMPILER_VERSION} VERSION_LESS 8) OR
	("${CMAKE_CXX_COMPILER_ID}" STREQUAL "Clang" AND NOT ${CMAKE_CXX_COMPILER_VERSION} VERSION_LESS 10))
	target_compile_options(${target} PRIVATE "-ffile-prefix-map=${CATCH_DIR}=.")
	endif()
	endfunction()
