With PKG_CONFIGURE _PATH you enable finding the right compiler flags
for compilation. However, this does not help you with the necessary
run time linking, since you seem to be building dynamic libraries. One
way forward might be:

* Build a static version of LAPACKE
* Build a static version of your dependency
* Build your package linking with your static libs and BLAS/LAPACK as
described in WRE.
