Subject: build: allow passing SOVERSION value for dynamic library
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=bc92a280186f9becc53c0f17e4e43cfbdeec7e7b;p=project%2Flibnl-tiny.git

build: allow passing SOVERSION value for dynamic library

In order to prepare for proper ABI handling in the OpenWrt package of
libnl-tiny, add an option to specify the library SOVERSION value when
invoking CMake.

Let the library SOVERSION default to `1` as first ABI version as the
library is stable and there's been no incompatible changes since it's
inception in 2009.
