I have used FindLAPACK quite a bit in the past without issues for my
FreeEOS project. So your report surprised me.  However, on further
investigation, it turns out you have found a recursion introduced
between 2.8.5 and 2.8.6 which explains my good prior results and your
bad results now.  Of course, to help the CMake developers avoid such
regressions I should have tested FreeEOS builds against 2.8.6 before
it was released, but although I did test the PLplot build that way, I
forgot to do such a test for FreeEOS.

I hope your patch is quickly accepted by the CMake developers for
2.8.7 since 2.8.6 will have to be black-listed for FreeEOS (and
presumably many other projects that use lapack/blas).
