hbp files with variable mapping to .hbm

[Eric Lendvai]

In one of my .hbp file I make reference to a .hbx like this:

${HB_VFP_ROOT}\build\win64\${HB_COMPILER}\${BuildMode}\hb_vfp.hbx

All the ${VariableName}  are environment variables

If I try to do the following:

${HB_FASTCGI_ROOT}\hb_fcgi\hb_fcgi_windows.hbm

It does not work.

I looked at the doc for hbmk2

https://github.com/Petewg/harbour-core/wiki/Harbour-Make-(hbmk2)

and it seems variables are to be used for only certain options.

Am I missing something?
