I am installing OpenBLAS because I need LAPACKE libraries which I cannot find on the current version of OpenBLAS on CRAN.
I add the libraries directory in my package to the PKG_CONFIG_PATH. Is this enough for the system to use my OpenBLAS library?

One of the dynamic libraries the package requires depends on LAPACKE library which usually integrated with BLAS and CBLAS in the same .so file (as I understand). CRAN has OpenBLAS already installed on the system. However, this OpenBLAS library does not maintain implementation of LAPACKE library. Thus, I have modified my configure file to install a standalone OpenBLAS library to use it.

This looks as if you are building OpenBLAS as a /dynamic/ library
installed in your package directory. This cannot work since the
run-time linker will not search your package directory for dynamic
libraries. You could build OpenBLAS as a /static/ library instead.
However, I am unsure why you want to build OpenBLAS in the first
place, since any R package can reliably link with the BLAS and LAPACK
versions used by R. See WRE on Makevars, BLAS_LIBS etc. for details.
