[CMake] CPack Components with NSIS and using InstallRequiredSystemLibraries

[Thomas Moelhave]

Hi there,

I've enjoyed using the new CPack component support[1] to generate funky
NSIS installers. However, the generated NSIS installer does not contain
the required MSVC (in my case, MSVC 9) redist dll's fuond by
InstallRequiredSystemLibraries.
The files are found correctly and are, in fact, included in the zip file
generated by the ZIP generator.


The install commands issued by InstallRequiredSystemLibraries does not
specify any component, and [1] says that:

---
CPACK_COMPONENTS_ALL:  A list containing the names of all components
that should be installed. The presence of this macro indicates that
CPack should build a component-based installer. Files associated with
any components not listed here or any installation commands not
associated with any component will not be installed.
---

However, CPack.cmake [2] has the following comment:
---
# CMake always generates a component named "Unspecified", which is
# used to install everything that doesn't have an explicitly-provided
# component. Since these files should always be installed, we'll make
# them hidden and required.
set(CPACK_COMPONENT_UNSPECIFIED_HIDDEN TRUE)
set(CPACK_COMPONENT_UNSPECIFIED_REQUIRED TRUE)
---


Do I have to do anything specific (other than
include(InstallRequiredSystemLibraries)) to make the NSIS generator
include them? I have tried using both  2.6.1 rc13 and yesterdays nightly
build.


Thanks for listening,
\ Thomas
