How to set wizard images in NSIS through CMake/CPack?

Question

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.

You can try to modify your NSIS.template.in file while running cmake using file command. For example: file(APPEND NSIS.template.in !define FILEID ${PROJECT_SOURCE_DIR}/path/to/file !define) – Reamy

I could modify the file this way.. or even better, copy it and then append to the copy. However, then the defines will end-up at the bottom of the script resulting in something like: MUI_WELCOMEFINISHPAGE_BITMAP is already defined (even though i have taken out the definition of it)... Although even if it didn't result in a preprocessing error, it still comes after the !insertmacro for MUI. – Ligature

Answer 1

Since you are already customizing the NSIS.template.in file, and it is a template presumably configured with the CONFIGURE_FILE() command, why not put the following in to your NSIS.template.in:

!define MUI_WELCOMEFINISHPAGE_BITMAP "@MY_CPACK_MUI_WELCOMEFINISHPAGE_BITMAP@"
!define MUI_UNWELCOMEFINISHPAGE_BITMAP "@MY_CPACK_MUI_UNWELCOMEFINISHPAGE_BITMAP@"

Then, in your CMakeLists.txt file where you set your other CPACK variables, add something like:

SET(MY_CPACK_MUI_WELCOMEFINISHPAGE_BITMAP
    "${CMAKE_SOURCE_DIR)/path/to/wizardInstall.bmp")
SET(MY_CPACK_MUI_UNWELCOMEFINISHPAGE_BITMAP
    "${CMAKE_SOURCE_DIR)/path/to/wizardUninstall.bmp")

Whereabouts

Thanks. But it seems these variables must have only "CPACK" prefix. Otherwise CPack ignores them and they would have an empty value in nsi. – Natalee

the path is not defined correctly, see: cmake.org/pipermail/cmake/2008-June/022085.html – Singlefoot

Answer 2

You do not need to compile whole NSIS to use/change these images.

They are present on every machine which has NSIS installed in ${NSISDIR}\Contrib\Graphics\Wizard\win.bmp

Use !define MUI_WELCOMEFINISHPAGE_BITMAP bmp_file in your .nsi script to change them.
