FindSYCLToolkit exectutes the DPC++ compiler using the
execute_process
CMake command to extract information about the compiler. To help debugging it tries to capture the output of the compilation to a file named Compile.log. However before this patch only the standard output was captured, even though the compiler will log errors to the standard error, and will almost certainly leave stdout empty.Capture both stderr and stdout to the same file, this is explicitly supported by CMake,
execute_process
