"Par for the course" as they say -- Windows has not standard library location<br>
so you will need an 'extra convention' as either the CRAN rules of installing<br>
a bunch of library in one jointly accessed directory, or by following<br>
per-library environment variables. Here is what RcppGSL does for GSL:<br>
<br>
PKG_CPPFLAGS= -I../windows/gsl-2.7/include -I../inst/include<br>
PKG_LIBS= -L../windows/gsl-2.7/lib${R_ARCH}${CRT} -lgsl -lgslcblas<br>
<br>
all: clean winlibs<br>
<br>
winlibs:<br>
"${R_HOME}/bin${R_ARCH_BIN}/Rscript.exe" "../tools/winlibs.R"<br>
<br>
clean:<br>
rm -f $(SHLIB) $(OBJECTS)<br>
<br>
ie it can just assume GSL is present. CRAN documents somewhere what libraries<br>
yu can expect; I cannot from the top of my head recall if LZMA is part of<br>
that set.<br>
<br>
Portable development is hard for a reason. Operating systems are idiosyncratic.<br>
