CPack NSIS组件未指定

Question

Behold the following fairly trivial CMake file:

cmake_minimum_required(VERSION 3.7)

add_library(libdice SHARED lib.cpp)

set_target_properties(libdice PROPERTIES
    PREFIX ""
    OUTPUT_NAME "Dice"
    PUBLIC_HEADER "lib.h"
)

install(TARGETS libdice
    RUNTIME DESTINATION "lib"
    LIBRARY DESTINATION "lib"
    PUBLIC_HEADER DESTINATION "include"
    COMPONENT sdk
)

set(CPACK_PACKAGE_NAME "Dice SDK")
set(CPACK_GENERATOR "NSIS")

include(CPack)

cpack_add_component(sdk)

With this lib.h :

#pragma once

int sides_of_a_dice();

And lib.cpp :

int sides_of_a_dice()
{
    return 6;
}

So if I nmake package for this on Windows it for some reason puts Dice.dll in an Unspecified component, even thought the component is clearly specified. Even weirder, the public headers ( lib.h ) correctly go in the sdk component.

CPack: Create package using NSIS
CPack: Install projects
CPack: - Run preinstall target for: Project
CPack: - Install project: Project
CPack: -   Install component: Unspecified   <- Why??!
CPack: -   Install component: sdk
CPack: Create package

What is going on?

Answer 1

According to documentation for install command, every specification of file's type (like RUNTIME , LIBRARY or PUBLIC_HEADER ) starts its own install clause , to which all other options are applied.

That is, option COMPONENT sdk is applied only to file's type PUBLIC_HEADER .

Other files ( RUNTIME , LIBRARY ) have component option unspecified .
