CMake, libexecinfo, ${LOCALBASE}/lib and ldconfig

[Alexandr Kovalenko]

Hello,

I'm working on 5.5.33a MariaDB port now and got trouble making cmake
to find libexecinfo (stub for linuxish backtrace() function).

I'm desperate now in trying to fight this thing:

Determining if the function backtrace exists failed with the following output:
Change Dir: /usr/ports/databases/mariadb55-server/work/mariadb-5.5.33a/CMakeFiles/CMakeTmp

root at vbox:~ # ldconfig -r | grep execinfo
        141:-lexecinfo.1 => /usr/local/lib/libexecinfo.so.1

Could anyone, please, explain me, why clang can't see libexecinfo
during link phase and how to fix it?

Thanks in advance!
