Even if the libraries are linked using absolute paths and resolved via
their <literal>install_name</literal> correctly, tests can sometimes fail
to run binaries. This happens because the <varname>checkPhase</varname>
runs before the libraries are installed.

This can usually be solved by running the tests after the
<varname>installPhase</varname> or alternatively by using
<varname>DYLD_LIBRARY_PATH</varname>. More information about this variable
can be found in the <citerefentry><refentrytitle>dyld</refentrytitle>
