# This is a "subroutine" that can be included to find the installation
|
|
# prefix of a package.
|
|
#
|
|
# The input variable is FIND_PREFIX, which is a list of VARNAME=<package>
|
|
# pairs, where "VARNAME" is the variable that will be set to the
|
|
# installation prefix for the package, and <package> is the ${PKGNAME}
|
|
# for the package.
|
|
#
|
|
# An example use is:
|
|
#
|
|
# FIND_PREFIX:= M4DIR=gm4
|
|
# .include "../../mk/find-prefix.mk"
|
|
# # ${M4DIR} now contains the installation prefix for the "gm4" package
|
|
#
|
|
|
|
