cmake fails to build with -DZSTD_PROGRAMS_LINK_SHARED=ON on windows #3554
Description
Hi,
building with -DZSTD_PROGRAMS_LINK_SHARED=ON results in:
fileio_asyncio.c.obj : error LNK2019: unresolved external symbol POOL_create referenced in function AIO_IOPool_createThreadPool
fileio_asyncio.c.obj : error LNK2019: unresolved external symbol POOL_free referenced in function AIO_IOPool_destroy
fileio_asyncio.c.obj : error LNK2019: unresolved external symbol POOL_joinJobs referenced in function AIO_IOPool_join
fileio_asyncio.c.obj : error LNK2019: unresolved external symbol POOL_add referenced in function AIO_IOPool_enqueueJob
programs\zstd.exe : fatal error LNK1120: 4 unresolved externals
The reason is fairly simple: The API in pool.h isn't made visible, therefore the references from programs/fileio.c can't see them.
Before 1598e6c a build like this worked. CC: @yoniko
It looks like it'd be easy enough to fix for POOL_create, POOL_free, there are public wrappers. But for the rest there isn't an obvious answer.
Regards,
Andres
