Check Prerequisites:

Ensure you have installed all the necessary prerequisites mentioned in the WebKit building guide. This includes Visual Studio, CMake, Python, Git, and other tools.
Environment Setup:

Make sure your environment variables are set correctly. This includes paths for tools like Python, Git, CMake, and Visual Studio.
Ensure Correct Version of Dependencies:

Sometimes, specific versions of dependencies are required. Double-check the WebKit documentation for any version-specific instructions.
Verify Include Paths:

The errors indicate missing header files (FixMath.h, CVBase.h, etc.). Ensure these files exist in the expected directories.
Check your project settings in Visual Studio to make sure the include paths are correctly configured. This can be done by going to Project Properties > C/C++ > General > Additional Include Directories.
Update and Sync Repository:

Make sure your local WebKit repository is up-to-date with the latest changes. Run the following commands to update and sync:
git pull origin main
Tools/Scripts/update-webkit
Install Additional Dependencies:

For QuickTime headers (like Movies.h), you may need to install the QuickTime SDK if it's not already included. This SDK might be required for the files in question.
Reconfigure and Rebuild:

Sometimes, reconfiguring the build setup can resolve path issues. Run CMake again to regenerate the project files:
Tools/Scripts/build-webkit --release
Detailed Steps for Missing Include Files
Example for FixMath.h:

Locate FixMath.h within your WebKit directory. If it's missing, you may need to obtain it from the QuickTime SDK.
Add the directory containing FixMath.h to your project's include directories:
In Visual Studio: Project Properties > C/C++ > General > Additional Include Directories.
Repeat similar steps for other missing headers like CVBase.h, CFNumber.h, CFData.h, GXMath.h, ImageCompression.h, and Movies.h.

Community and Documentation
If the above steps do not resolve the issues, consider reaching out to the WebKit development community:

WebKit Mailing List: webkit-dev
WebKit IRC Channel: #webkit on irc.freenode.net
You can also refer to additional documentation and community forums for similar issues:

WebKit on Windows Documentation
WebKit GitHub Issues
Example Configuration for Include Paths in php.ini
[Paths]
; Make sure to replace 'path_to_sdk' with the actual path to the SDK or library directory
include_path = "path_to_sdk/QuickTimeHeaders"
