The search path for FIND_LIBRARY and FIND_PATH calls are constrcted
in c++, like this:

//----------------------------------------------------------------------------
void
cmMakefile::GetIncludeSearchPath(const std::vector<std::string>& callerPaths,
                                 std::vector<std::string>& path)
{
  // Add paths configured into the cache for this project.
  if(const char* cmakeIncludePath = this->GetDefinition("CMAKE_INCLUDE_PATH"))
    {
    cmSystemTools::ExpandListArgument(cmakeIncludePath, path);
    }

  // Add paths in the user's environment.
  cmSystemTools::GetPath(path, "CMAKE_INCLUDE_PATH");
  cmSystemTools::GetPath(path, "INCLUDE");

  // Add paths given by the caller.
  path.insert(path.end(), callerPaths.begin(), callerPaths.end());

  // Add standard system paths.
  cmSystemTools::GetPath(path);
}

//----------------------------------------------------------------------------
void
cmMakefile::GetLibrarySearchPath(const std::vector<std::string>& callerPaths,
                                 std::vector<std::string>& path)
{
  // Add paths configured into the cache for this project.
  if(const char* cmakeLibPath = this->GetDefinition("CMAKE_LIBRARY_PATH"))
    {
    cmSystemTools::ExpandListArgument(cmakeLibPath, path);
    }

  // Add paths in the user's environment.
  cmSystemTools::GetPath(path, "CMAKE_LIBRARY_PATH");
  cmSystemTools::GetPath(path, "LIB");

  // Add paths given by the caller.
  path.insert(path.end(), callerPaths.begin(), callerPaths.end());

  // Add standard system paths.
  cmSystemTools::GetPath(path);
}

So, the search order is:

1. search the cmake variable CMAKE_*_PATH
2. search the env variable CMAKE_*_PATH
3. search the LIB or INCLUDE env variable.
4. search the paths specified in the call to FIND_*
5. search the system PATH
