This commit aims at improving speed by using better caching.
- Makefile, cache.mk: Split .cache.mk up
To allow caching of runtime path variables which are
project-specific, split .cache.mk up in .cache-project.mk and
.cache-projects.mk
- ldlibpath.mk: Cache ldlibpath, exepath and pythonpath
Place the output of $(call proj_query ldlibpath), $(call
proj_query, exepath) and $(call proj_query pythonpath) in
JW_PKG_LD_LIBRARY_PATH, JW_PKG_EXE_PATH, and JW_PKG_PYTHON_PATH
respectively, and cache the variables in make/.project-cache.mk.
- cache.mk: Use = instead of :=
Recursively expanded variables are nearly as fast as := variables
if the assigned value is a fixed string. And sometimes it's not,
rightly so, because variables get assigned below, as with
JW_PKG_XXX for instance.
- cache.mk: Use $(TOPDIR) as variable values
Replace absolute references to project's topdir by $(TOPDIR) with
sed. As soon as the project queries produce absolute paths, they
will be transformed into relative paths which allow the code base
to be moved to a different location and still remain functional
without a rebuild.
