cmake + configure_file + script perl

[Laurent Montel]

Hi,
I must generate script perl from a configure_file.
I have a lot of script perl where I must specify into some variable
example:
convert.pl.in
into I must change $src=@kde_datadir@
I change it with $src=${KD4_DATADIR}

but as it's perl script I have a lot of "$<variable>"
=> cmake try to convert it.

do you have an idea to convert it without try to convert other variable ?

Thanks
Regards
