[CMake] [CPack] Empty package while using component with NSIS on Win64 platform.

[Alexandre Fournier]

The new example is working, I guess I did not have the latest one, that is good news to me.

I removed all absolute path from install command : 

INSTALL(TARGETS triage 
        RUNTIME 
        DESTINATION bin 
        COMPONENT triageApp)

I disabled the SET_DESTDIR and remove the command after the include(CPack) and decided to use directly CPACK_COMPONENT_... variable.

set(CPACK_COMPONENT_TRIAGEAPP_DISPLAY_NAME "blabla")
	
set(CPACK_COMPONENT_TRIAGEAPP_DESCRIPTION
        " blabla ")
        
set(CPACK_COMPONENT_TRIAGEAPP_GROUP "Applications")
	
set(CPACK_COMPONENT_GROUP_APPLICATIONS_EXPANDED ON)
set(CPACK_COMPONENT_GROUP_APPLICATIONS_DESCRIPTION
        " blabla ")
        
set(CPACK_ALL_INSTALL_TYPES Full Developer)
set(CPACK_INSTALL_TYPE_FULL_DISPLAY_NAME "Everything")
set(CPACK_COMPONENT_SURGICALLANDMARKADJUSTMENTAPP_INSTALL_TYPES Developer Full)
set(CPACK_COMPONENT_TRIAGEAPP_INSTALL_TYPES Developer Full)

It does not create the package anymore and makes an error when trying to install the first component.  

CPack: Enable Verbose
CPack Verbose: Read CPack config file:
CPack Verbose: Read CPack configuration file: C:/projects/test3/release

ack_Packages/win64/NSIS
CPack: Install projects
CPack: - Install project: Project
CPack: -   Install component: triageApp
CPack Error: Error when generating package: Project

I compared the example with my files and it is mostly the samething except that INSTALL command are not in the same CMakeLists.txt file.  Could that be the root of the problem?

This one SHOULD NOT be set for a NSIS/WIndows package

in fact beginning with CMake 2.8.6 it is seldom useful to set CPACK_SET_DESTDIR to ON in any case.

if ${BUILD_ROOT} is an absolute path this won't work.

Trust me you don't want to set CPACK_SET_DESTDIR to ON.
In the same way "absolute DESTINATION install path" will NOT work on Windows.

Did you use the "Start" archive or did you use the "final":
http://www.cmake.org/Wiki/File:ComponentExample.zip

> The example is not working at all, NSIS got errors:

May be the example is not up to date, but using http://www.cmake.org/Wiki/File:ComponentExample.zip
I can build an NSIS installer using CMake 2.8.8 and NSIS 2.46.
(on Linux with some crosstools but concerning the generated  NSIS project and NSIS processing it looks just fine).

Are you using some custom build of NSIS ?
Like 64 bits
http://public.kitware.com/Bug/view.php?id=13203
or svn trunk?
http://public.kitware.com/Bug/view.php?id=13202

if not it should work.
