> {{ModuleTest::SetUpTestCase()}} and the various {{libraries::paths()}} is stout assume that updating {{LD_LIBRARY_PATH}} or {{DYLD_LIBRARY_PATH}} is sufficient to alter the search path used by dlopen(3). It is not; those environment variables are only bound at program load.
> My preference is to fix this by requiring the clients of {{DynamicLibrary}} to always pass in an absolute path and to remove all mention of these environment variables.
> FWIW, the tests in {{ModuleTest::SetUpTestCase()}} only work because the libtool wrapper script sets up the library path to the expected value prior to running the tests.
