kowsiks 2fc0e060ef BaseTools/build.py: Use full source file path for dependency generation
During Silent build,NMAKE suppresses the command echo entirely.
As a result, the only output in ProcOut is the
MSVC compiler’s output lines.
Without the command echo, there is no full path in the output to
identify which source file is currently being compiled.
For unique basenames this is not an issue, but for namesake files
(for example, AmdSev.c located in different directories),
it is impossible to determine which file’s includes are being listed.

This change improves dependency generation for MSVC builds by introducing
explicit handling for source files with duplicate basenames
(namesake sources). A new variable current_source_abs is added to
consistently track the resolved absolute path of the active source file
instead of repeatedly recomputing it from SourceFileAbsPathMap.
To correctly resolve namesake files in silent builds
(where compiler commands are not echoed), a namesake_queue is introduced,
which preserves source ordering and sequentially maps basename occurrences
to their corresponding full paths.
Additionally, a cc_cmd_in_output flag is implemented to detect the presence
of compiler command lines in the output stream; when present,
source paths are derived directly from command-line arguments, otherwise
the queue-based resolution is used. This ensures correct mapping of
basenames to absolute paths across the silent builds, fixing incorrect
dependency generation when multiple source files share the same name.

  Note: New build instructions are available. It is recommended to start with
  the new instructions if learning how to build edk2 and/or BaseTools for the
  first time. This page is retained for reference.

New instructions: `Build Instructions`_

.. _`Build Instructions`: https://github.com/tianocore/tianocore.github.io/wiki/Build-Instructions

This directory contains the EDK II build tools and template files.
Templates are located in the Conf directory, while the tools executables for
Microsoft Windows Operating Systems are located in the Bin\\Win32 directory, other
directory contains tools source.

Build step to generate the binary tools
---------------------------------------

Windows/Visual Studio Notes
===========================

To build the BaseTools, you should run the standard vsvars32.bat script
from your preferred Visual Studio installation or you can run get_vsvars.bat
to use latest automatically detected version.

In addition to this, you should set the following environment variables::

 * EDK_TOOLS_PATH - Path to the BaseTools sub directory under the edk2 tree
 * BASE_TOOLS_PATH - The directory where the BaseTools source is located.
   (It is the same directory where this README.rst is located.)

After this, you can run the toolsetup.bat file, which is in the same
directory as this file.  It should setup the remainder of the environment,
and build the tools if necessary.

Unix-like operating systems
===========================

To build on Unix-like operating systems, you only need to type ``make`` in
the base directory of the project.

Ubuntu Notes
============

On Ubuntu, the following command should install all the necessary build
packages to build all the C BaseTools::

 sudo apt install build-essential uuid-dev
