externalNativeBuild { cmake { arguments "-DCMAKE_MAKE_PROGRAM=$YOUR_CMAKE_NINJA_PATH$", "-DCMAKE_OBJECT_PATH_MAX=1024" } }

Note: Replace the value of $YOUR_CMAKE_NINJA_PATH$ with the actual path where Ninja is installed. For example: E:\SDK\cmake\3.22.2\bin\ninja.exe

4. Enable Long Path Support in Windows

To support long file paths in Windows, run the following PowerShell command:

New-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Control\FileSystem" -Name "LongPathsEnabled" -Value 1 -PropertyType DWORD -Force

This command allows Windows to support paths longer than 260 characters.
