Unable to find header file libssh_version.h

when compile file “”exec.c“” , Unable to find header file libssh_version.h
and I couldn't find the header file “libssh_version.h”“” 。But I found similar files “libssh_version.h.cmake”“”
so how to solve it? Thank you very much！

Start by examining how exec.c is compiled and how libssh_version.h.cmake is used in the build configuration. Verify whether the missing header is generated or expected from configuration, then reproduce the compilation failure and confirm that exec.c builds with libssh_version.h available.
