I see that there is no CPACK_xxx variable for changing the wizard image(s) in NSIS (like CPACK_PACKAGE_ICON). So I copied the NSIS.template.in and modified it. I could do something like:
!define MUI_WELCOMEFINISHPAGE_BITMAP "C:\work\project\img\wizardInstall.bmp" !define MUI_UNWELCOMEFINISHPAGE_BITMAP "C:\work\project\img\wizardUninstall.bmp"
and it will work. However, the source code goes in a repository where many developers colaborate, and it's not really good idea to keep absolute paths there. I tried to find some way to get my source path, and somehow create the image path from that one, but to no avail.
So, if someone knows how can i set the wizard images in NSIS, or pass the source dir (and create the path from it) to my template file, please let me know.
