I see two options for compiling your packages.
1. You do

  R CMD build J:\TempWork\BHPMF_CRAN_Archive\

which should produce something like BHPMF_1.0.tar.gz (1.0 being an
example of package version). Then
  R CMD check J:\TempWork\BHPMF_1.0.tar.gz (put the true name of the 
produced tarball here). After that you can see all used flags and 
options in J:\TempWork\BHPMF.Rcheck\00install.out file.

2. In R session having J:\TempWork\BHPMF_CRAN_Archive\ as working dir you do

  devtools::load_all()

The first option is better suited for final stages of your dev work 
while the second one is more appropriate for your iterative dev cycles.

Best,
Serguei.
