Hello, in the ExternalProject_add function, I would like to access to DOWNLOAD_DIR to download a patch (for ARPACK). So, I define my patch command like this:
================================================== PATCH_COMMAND cd <DOWNLOAD_DIR> && wget /myurl/mypatch.tar.gz && cd <SOURCE_DIR> && tar xvzf <DOWNLOAD_DIR>/mypatch.tar.gz ================================================== However, I get the following error: [ 5%] Performing patch step for 'arpack' /bin/sh: 1: cd: can't cd to <DOWNLOAD_DIR> make[2]: *** [third-party/arpack/stamp/arpack-patch] Erreur 2 make[1]: *** [CMakeFiles/arpack.dir/all] Erreur 2 make: *** [all] Erreur 2 Do you see where I make a mistake? Thank you! Cédric
