在makefile中使用sed用变量

Question

我进行了广泛的搜索并找到了许多类似的问题，但据我所知，没有找到真正做我想要的东西的问题。

在这里是最接近的问题：

在makefile中使用sed;如何逃避变量？

我想在makefile内部做的非常简化的版本是

sed s~foo~${BAR}~ where

$BAR

是我的makefile中的一个变量。显然，我想用当前发生的文本

foo

replace replace replace replace replace replace

$BAR 由于被要求，这是完整版本：

请注意，目标是让makefile成为posix。

Makefile（仅相关部分）：${BAR}

rsync -avz --exclude $SHORTCHAPTERDIR src/ tmp/src_diff_$DIFFBRANCH/ # copy all source files to tmp except chapters (because they're already there)

sed -i.bak -E 's~^([[:blank:]]*\subimport{chapters/}{[[:alnum:]_]+)}~\1-$BRANCH-diff-$DIFFBRANCH}~' tmp/src_diff_$DIFFBRANCH/iuf-rulebook.tex 
# this replaces \subimport{chapters/}{01_general} with \subimport{chapters/}{01_general-$BRANCH-diff-$DIFFBRANCH} with the variables expanded
# so that the iuf-rulebook.tex uses the diffed chapters
# the -i.bak is required so SED works on OSX and Linux
rm -f tmp/src_diff_$DIFFBRANCH/*.bak # because of this, we have to delete the .bak files after
