cmake - How to set the shared library soversion at the build-time? -

-

this sets version @ cmake-time:

set_target_properties(${this_lib} properties soversion ${project_version})

but use scripts extract info git (is dirty or wrong branch, etc).

for example, can generate version.cpp info @ build-time:

add_custom_command(     output ${cmake_current_binary_dir}/version.cpp     depends         ${git_commit_dirtiness_file}     command ${cmake_command}         -dsrc=${cmake_current_source_dir}/version.cpp.in         -ddst=${cmake_current_binary_dir}/version.cpp         -p ${cmake_source_dir}/cmake/configure-file.cmake )

so executable has various information source tree state.

how same kind of operation on soversion, in package lib appear libmy.so.0.0.1.sha.~dirty example?
