This patch introduces the following functions for Makefiles:
check_dep_exec <exe>
Check existence of the executable <exe>
check_dep_pylib <lib>
Check existence of the python library <lib>
Calling and evaluting the functions will create a check_xxx target and add the
target to the variable BUILD_DEPS. Thus it is sufficient to add the following
to a Makefile for checking a number of build dependencies.
include deps.mk
$(eval $(call check_dep_exec,python))
$(eval $(call check_dep_pylib,Sphinx))
all: $(BUILD_DEPS) ...
v4 -> v5:
* No changes.
v3 -> v4:
* No changes.
v2 -> v3:
* No changes.
v1 -> v2:
* New in v2.
