I want to add /usr/mylocal/include to standard system include directory, but
don't want to use -I/usr/mylocal/include, How can I make it.
The problem is I compiled library A, and installed to /usr/mylocal/include,
and then compile library B, which depends on A, so I have to make sure
configure program search headers in /usr/mylocal/include first, then other
standard system include directory. My system has another version A which
comes from the Fedora release, and I don't want B to use headers from this
Fedora release.
Thanks.
