cmake prefix buildink question

[Manuel Bouyer <bouyer%antioche.eu.org@localhost>]

Hello,
I'm trying to build wip/freecad, and it chokes because cad/occt's cmake file
includes path to the buildink directory:
fgrep .buildlink /usr/pkg/lib/cmake/opencascade/OpenCASCADEVisualizationTargets.cmake 
  INTERFACE_LINK_LIBRARIES "TKernel;TKMath;X11;fontconfig;/usr/tmp/cad/occt/work/.buildlink/lib/libfreeimage.so;/usr/tmp/cad/occt/work/.buildlink/lib/libfreetype.so"
  INTERFACE_LINK_LIBRARIES "TKBRep;TKMath;TKernel;TKService;TKShHealing;TKTopAlgo;TKG2d;TKG3d;TKGeomBase;TKMesh;TKGeomAlgo;TKHLR;GL;X11;/usr/tmp/cad/occt/work/.buildlink/lib/libfreetype.so"

I guess this is because the installed files uses the same value as the one
used to build the package.
The attached patch works around this, but is there a better way to fix this ?
