spdlog/include/spdlog/details/periodic_worker-inl.h
Cristian Morales Vega 7cdd65075c "#include" <spdlog/.*> instead of "spdlog/.*"
The meaning of using quotes to #include is implementation defined, so it
may or not may be what we want. At least POSIX
(https://pubs.opengroup.org/onlinepubs/9699919799/utilities/c99.html)
says: "headers whose names are enclosed in double-quotes ( "" ) shall be
searched for first in the directory of the file with the #include line",
so not what we want since "spdlog" ends up twice in the path.
