[R-sig-Debian] Installing package fails at "testing if installed package can be loaded from temporary location"

[Sam H]

Dirk, thank you a thousand times.

Indeed, src/Makevars was wrong. I modified Makevars so that now looks like
the below and the package now compiled and linked properly.
CXX_STD = CXX11

PKG_LIBS += $(SHLIB_OPENMP_CXXFLAGS) $(LAPACK_LIBS) $(BLAS_LIBS) $(FLIBS)
$(shell ${R_HOME}/bin/Rscript -e "RcppParallel::RcppParallelLibs()")
PKG_CXXFLAGS = $(SHLIB_OPENMP_CXXFLAGS) -I../inst/include

Best,
Sam
