Thanks for filing the issue. I've managed to reproduce this bug on my machine:

$ meson builddir
...
Run-time dependency zlib found: YES 1.2.11
Run-time dependency liblzma found: YES 5.2.4
Run-time dependency liblz4 found: NO (tried pkgconfig and cmake)

meson.build:124:5: ERROR: Unknown variable "enable_static_runtime".

And I can confirm that your proposed changes fix the issue on my machine:
After patch

$ meson builddir
...
Message: Enable multi-threading support
Windows resource compiler: Microsoft (R) Windows (R) Resource Compiler Version 10.0.10011.16384
Program ../InstallSymlink.py found: YES (c:\python38\python.exe C:\Users\Bimba Shrestha\workspace\zstd1\build\meson\programs\../InstallSymlink.py)
Build targets in project: 5

I'll put up a PR soon.
