A number of different packages will install foo-config in the PATH to
make it easy to figure out if the package installed and what options
should be used.
Examples include:
autoopts-config
cups-config
curl-config
libgcrypt-config
libpng-config
Anyway, I was wondering if libevent could install something similar.
I'm looking for path information (include and library) and any needed
CPP, library, etc. flags.
libevent provides pkg-config files that should do the same as these helper programs. You can run shell program 'PKG_CONFIG_PATH=/foo/libevent/lib/pkgconfig/ pkg-config' to get the information you desire on stdout. pkg-config also has nice Autoconf macros.
