Including spdlog 1.8.0 from .cu files (NVCC compilation) fails

[harrism]

Building CUDA source files (.cu) using NVCC fails in 1.8.0 (works in 1.7.0) with errors like this:

_deps/spdlog-src/include/spdlog/fmt/bundled/format.h (3677): error: a literal operator template must have a template parameter list equivalent to "<char ...>"

This is fixed in the master branch of fmt lib:
fmtlib/fmt#1818

I am still having the same error with nvcc 12.1 and spdlog v1.14.1

The following patch solved this problem on my end, basically the same as the solution in the upstream fmt repo.
