Didn't work
```
make rpkg
Makefile:227: "USE_LAPACK disabled because libraries were not found"
Makefile:355: WARNING: Significant performance increases can be achieved by
installing and enabling gperftools or jemalloc development packages
mkdir -p R-package/inst/libs
cp src/io/image_recordio.h R-package/src
cp -rf lib/libmxnet.so R-package/inst/libs
if [ -e "lib/libdnnl.so.1" ]; then \
cp -rf lib/libdnnl.so.1 R-package/inst/libs; \

Loading required package: usethis
Error: Can't find 'R-package'.
Execution halted
make: *** [Makefile:697: rpkg] Error 1
```
my makefile (in mxnet root) now looks like this
```
R CMD INSTALL R-package
Rscript -e "require(mxnet); mxnet:::mxnet.export('R-package'); warnings()"
touch R-package/NAMESPACE
Rscript -e "devtools::document('R-package');warnings()"
R CMD INSTALL R-package
```
Also the warnings look like it is trying to build mxnet from scratch, I have
already built successfully with
```
make -j4 USE_OPENCV=1 USE_BLAS=openblas USE_CUDA=0 USE_CUDNN=0 USE_MKLDNN=1
USE_JEMALLOC=1
```
So why is it still saying "WARNING: Significant performance increases can be
achieved by installing and enabling gperftools or jemalloc development
packages"?
