how to use environment variable in configure

[newcfd]

export APP_HOME = /something/
is it possible to use it in configure --prefix=$APP_HOME?

I also want to use it in ccmake . settings. It seems that I can not do it.

Any help? Thanks.

configure --prefix=$APP_HOME works. But in the Makefile absolute path is used. I would prefer to have $APP_HOME in the Makefile.

I tried configure --prefix=${$APP_HOME}. configure does not like it

try

--prefix='$(APP_HOME)'

the single quotes should prevent shell expansion

Thanks for your reply. the quotes do prevent shell expansion.
But configure adds the source dir in front of $(APP_HOME)
For example, if the source is in /home/src, install dir becomes /home/src/$APP_HOME

try

--prefix='$(APP_HOME)'

the single quotes should prevent shell expansion
