9521	"""make install"" for a bundle on Windows very slow"	Tom Goddard	Greg Couch	"If I do ""make install"" in the vive bundle directory on Windows (vive.cgl.ucsf.edu) it takes about 25 seconds, of which 21 seconds it has not output anything.  If I to do makes in fast succession (< 10 seconds apart) then it takes just couple seconds.

I tracked this down to being a cygwin make problem caused by these lines in our Makefile.bundle

{{{
ifeq (,$(wildcard /app))
CHIMERAX_APP = $(wildcard $(TOP)/ChimeraX*.app)
else
CHIMERAX_APP = $(wildcard /app)
endif
}}}

In fact with cygwin make the following Makefile takes 21 seconds to do a make clean

{{{
ifeq (,$(wildcard /app))
endif

clean:
        echo cleaned
}}}

I tried updating cygwin and the problem persists.

Not sure why we are testing if /app exists.  Also is there an idiom to do that without $(wildcard)?  That seems like overkill for checking if a directory exists.

For now I comment out that check for /app and my ""make install"" being done 100 times a day developing VR code has now saved me an hour!"	defect	assigned	moderate		Build System								all	ChimeraX
