[CMake] packageConfig mishap

[Nagy-Egri Máté Ferenc]

Hi!
I'm trying to use the package config file of clFFT (big congrats on providing one), but it seems I'm doing something wrong. Without using FindclFFT.cmake, CMake fails to find the config files, both on Windows and Ubuntu. On Windows I have a registry entry such as:
PS C:\Users\Matty> Get-ItemProperty -Path HKCU:\SOFTWARE\Kitware\CMake\Packages\


clFFT_2.6.1  : C:\Kellekek\AMD\clFFT\2.6.1\CMake
PSPath       : Microsoft.PowerShell.Core\Registry::HKEY_CURRENT_USER\SOFTWARE\Kitware\CMake\Packages\
PSParentPath : Microsoft.PowerShell.Core\Registry::HKEY_CURRENT_USER\SOFTWARE\Kitware\CMake
PSChildName  : Packages
PSDrive      : HKCU
PSProvider   : Microsoft.PowerShell.Core\Registry

and also on Linux:

mnagy at opteron:~/Build/clFFT_Test/opteron$ cat ~/.cmake/packages/clFFT_2.6.1.package
/opt/AMD/clFFT/2.6.1/lib64/cmake/clFFT

but every time I configure a project, I get the following error:

mnagy at opteron:~/Build/clFFT_Test/opteron$ cmake -D CMAKE_BUILD_TYPE=Release ~/Develop/clFFT_Test/

CMake Warning at CMakeLists.txt:39 (find_package):
  By not providing "FindclFFT.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "clFFT", but
  CMake did not find one.

  Could not find a package configuration file provided by "clFFT" with any of
  the following names:

    clfft-config.cmake

  Add the installation prefix of "clFFT" to CMAKE_PREFIX_PATH or set
  "clFFT_DIR" to a directory containing one of the above files.  If "clFFT"
  provides a separate development package or SDK, be sure it has been
  installed.

Without providing CMAKE_PREFIX_PATH on the command-line, the paclage config files do not work. What exactly am I doing wrong? According to the CMake wiki

http://www.cmake.org/Wiki/CMake/Tutorials/Package_Registry

it should be working automatically (as is the whole purpose of packages).
