First off, life would get *so* much easier for you if you just let
everything put itself in it's default location: under /usr/local

To "keep it fixed" you need to export the variable in your .profile,
.bashrc, etc so that the next time you login or pop open a new window,
the variable is set.

More of the same.  Just take the default config args and install under
/usr/local.  E.g.,

  $ cd .../cppunit-<x.y.z>
  $ ./configure
  $ ./make
  $ sudo make install

  $ sudo ldconfig


You may want to consider investing in a book on Linux system
administration.  It's a good investment.
