-I tells the pre-processor where to find the headers, but it doesn't

you'll have to
use AC_CHECK_LIBS, but you probably want to start using
pkg-check. I've found that it's biggest advantage is that it
doesn't spoil configure caches. Using AC_CHECK_LIBS while
developing in an environment where libraries that are in use are
constantly being installed/uninstalled causes configure caches to be
totally useless without pkg-config.
Thing is, I disabled all of that checking in the configure.ac file. Is
there a way to set it in Makefile.am?
Doing the checks in configure.ac is the easiest way to get
the proper -l and -L flags into the Makefile.
I'm looking at this from the
below link:

Can I set noinst_LTLIBRARIES to do it for me?
I'm not sure I understand your question. Specifying
noinst_LTLIBRARIES tells
automake that your Makefile should include rules to create a
particular
library, but it doesn't pass any information to the linker about the
location
of other libraries. Are you having trouble linking an application
against
a convenience library that you are using, or are you having trouble
linking an application against a library that is external to this
particular
project?
CPPFLAGS will only provide the -I (eye) flags, but you need -l (el)
and -L as well.
If you do the check in configure.ac using AC_CHECK_LIBS, you need
do nothing in your Makefile.am. Or you can specify LIBS at configure
time
or in configure.ac. Or, if you are not interested in ever using the
software
on a different platform or a different configuration (libraries
installed in
other locations than they are today on your maching) you can probably
get away with hardcoding AM_LDFLAGS in Makefile.am, but **this is
usually
a bad idea**.
The libraries are internal to the project. They're simply in a
different directory.
