CMake Support for Blocked Pfaffian

[xrq-phys]

• Added CMake support to blocked Pfaffian update.
• NOTE: Unlike the traditional in-place mVMCconfig.sh which builds BLIS locally, the CMake strategy downloads a system-specific prebuilt artifact from xrq-phys/[email protected]+arm.
• CMake option PFAFFIAN_BLOCKED is created. If the option is set to OFF, no blocked-Pfaffian would be built. No BLIS artifact would be downloaded, either.
• Configs in /config set PFAFFIAN_BLOCKED to ON except for apple.cmake (due to GitHub CI unavailability) and gcc.cmake (since it's more or less system-agnostic and the auto-detection is not guaranteed to always work).

One more thing done in this PR: User is able to use the environment variable VMC_BLOCK_UPDATE_SIZE to override the default block size of Pfaffian update. As this does not affect computational results, I didn't add it to readdef.c.

@xrq-phys
thank you for your great efforts!
I merged PR.

I now checked and found that an error occurs in using cmake (not using PFAFFIAN_BLOCKED).

CMake Error at CMakeLists.txt:74 (add_subdirectory):
add_subdirectory given source "src/pfapack/fortran" which is not an
existing directory.

This may be caused by the incorrect link for pfapack.
Could you check the origin of this error?

I made Pfapack a submodule. Sometimes *git submodule update -r -i *might fail to load due to clutters left inside the old directory. Could you try cleaning? Best,

ok. Using git submodule update -r -i, cmake now works.
thank you!

Btw with this CMake+prebuilt BLIS, Fugaku compilation no longer needs submitting compile.sh.

Cheers. 😜
