Libraries have been installed in:
/home/tmp/cphalcon/build/64bits/modules
If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR‘
flag during linking and do at least one of the following:
- add LIBDIR to the `LD_LIBRARY_PATH‘ environment variable
during execution
- add LIBDIR to the `LD_RUN_PATH‘ environment variable
during linking
- use the `-Wl,--rpath -Wl,LIBDIR‘ linker flag
- have your system administrator add LIBDIR to `/etc/ld.so.conf‘
See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.
