[BUG] `rapids-logger` cannot find `spdlog`

[ttnghia]

When a cmake project include cudf like this: https://github.com/rapidsai/cudf/blob/5868839f9fc88de50594e6067c7b15265523cdb1/java/src/main/native/CMakeLists.txt#L95

rapids_find_package(cudf REQUIRED)

Then an error shows up saying that rapids-logger needs spdlog but cannot find it:
