I have strange results when I play with features.
The exact same code will randomly return "yes" or "no".

In Sconstruct, I have this

if 'triangulation' in env['features']:
       
ok=conf.CheckLibWithHeader('TesselationWrapper','TesselationWrapper.h','CXX',call=False,autoadd=1)
       if not ok: featureNotOK('triangulation')

and in my profile, I have :

CPPPATH = '/home/bruno/YADE/yade-bzr/extra/triangulation'
LIBPATH = '/home/bruno/YADE/yade-bzr/extra/triangulation'

10 minutes ago, the library was found and the check returned "yes".
I removed CPPPATH from my profile to see the result : lib not found.
I put CPPPATH again : the library is still not found.

I feel like something is cached somewhere but I don't know what and where.

Another question : what is the relative path to 
'/home/bruno/YADE/yade-bzr/extra/triangulation', I'm sure ther is a 
symbol for that.

Thanks.
