Uses GenerateExportHeaders from cmake to export only symbols needed externally
This should only affect the library part, and to be more specific, the shared
library part. Cmake allows to generate a special header file through
GenerateExportHeader()[1]. This defines - amongst other - a SPDLOG_EXPORT
Symbol, that does the right thing, depending on compiler / OS. On Windows,
default is, if I recall correctly, that all symbols are not exported while
Linux does it the other way around. So this patch sets default to *not* export
symbols except those marked SPDLOG_EXPORT. Behaviour with Windows and Linux
should be the same. Also, I removed SPDLOG_BUILD_SHARED in favour of the
standard BUILD_SHARED_LIBS, which is a global symbol. This *might* give some
issues when used as add_subdirectory(), but I am not sure.
Also I made Threads::Threads private, so a depending cmake package does not
need to have find_package(Threads) on.
Why all that? On x86_64, gcc 8.3.0 .so code size reduction is:
811320 bytes original vs. 532536 now (~65% of the original). And, I *guess*,
this will resolve the issue that it is not possible to use shared libs
with windows. But I cannot test it, I only have Linux.
