## Intent: Derive a filesystem path relative to the active makefile.
## Primary use is loading adjacent tool config files.
## Immediate evaluation (:=) needed to preserve path context.
## Note: We could pass in var=MAKEFILE_LIST
## -----------------------------------------------------------------------
## Given:
## scalar Filename to construct a path for
## Return:
## scalar Constructed path for the given filename
## -----------------------------------------------------------------------
## Usage:
## groovy-check-conf := $(call path-by-makefile,.groovylintrc.json)
## groovy-cmd = npm-groovy-lint --config "$(groovy-check-conf)"
## -----------------------------------------------------------------------

## Intent: Improve function usability for path-by-makefilepath-by-makefile
## -----------------------------------------------------------------------
## Given:
## scalar A makefile variable name to define
## scalar Path within a makefile subdirectory to construct
## Return:
## scalar Constructed path for the given filename
## -----------------------------------------------------------------------
## Usage:
## $(call genpath-makefiles,tox-ini,tox.ini)
## $(info tox-ini = $(tox-ini))
## -----------------------------------------------------------------------
