how to build a library in a specified directory? |

I have two projects. One generates a shared library and the other uses it.
The library is to be installed in /usr/local/lib/ezproject, while the
project’s name is ezcommon. I have problems in both the projects.
ezcommon’s configure.ac,
…
AC_INIT(ezcommon, 3.0)
AC_DISABLE_STATIC
…
ezcommon's Makefile.am,
lib_LTLIBRARIES = libezcommon.la
libdir = $(exec_prefix)/lib/ezproject
includedir = $(prefix)/include/ezproject
Problem is, if user configure --libdir=..., the user's definition will be
ignored. How can I set libdir only when user does not assign it? (Since this
dir name is not same as project name, I cannot use pkglib_.)
The other question is how to check for this library in the other project,
named ezcmd.
ezcmd's configure.ac,
...
AC_CHECK_LIB([ezcommon], main,,AC_MSG_ERROR(...))
...
This check will fail, since ezcommon is installed in
/usr/local/lib/ezproject by default. Should I add LDFLAGS=-Lezproject or
sth.? And how? Or should I add this directory to system's link-search
directory?
Thank you very much.
