Undefined symbols for architecture arm64

Hey. I have a Apple Mach-O Linker (ld) Error during build Unity project in XCode 11.6
There are few undefined symbols:

"inflate", referenced from:
inflatestream in libSkyTrakSW.a(libcurlla-contentencoding.o)

"zlibVersion", referenced from:
Curlunencodegzipwrite in libSkyTrakSW.a(libcurlla-contentencoding.o)

"inflateInit2", referenced from:
inflatestream in libSkyTrakSW.a(libcurlla-contentencoding.o)

"inflateEnd", referenced from:
inflatestream in libSkyTrakSW.a(libcurlla-contentencoding.o)

"inflateInit", referenced from:
Curlunencodedeflatewrite in libSkyTrakSW.a(libcurlla-content_encoding.o)

libSkyTrakSW.a - is a static C++ library, that was built in XCode 11.6. The same project with the same library was successfully built some time ago with another version of Unity and XCode.

I have libz.tbd as requred library for linking on Build Phases tab.

What else should I do to fix this linking error? Thanks!
