[R] Using win-builder with static libraries

[Maxime Debon]

Dear All,

I am intending to build a package (pksmooth) on Linux to work on
Windows. Some c++ functions need c++ libraries (numerical recipes)
from a static library "libNR.a".
Building the package on Linux for Linux is allright. However, when
sending the 'pksmooth_1.0.tar.gz' to the online Windows builder
(win-builder.r-project.org),the compilation doesn't take into account
the library "libNR.a". Yet, it is included in the tar.gz file in a
'libs' folder and called in a makefile located in the 'src' folder.

Any comment will be appreciated,

Maxime
