I'm not sure you can.
install() rules are processed when CMake runs and generate all
cmake_install.cmake files.
then when CPack runs it triggers the install using the files generated at
CMake time.
So while you can achieve some conditional actions when CPack runs using
CPack project config file
https://cmake.org/cmake/help/v3.14/module/CPack.html#variable:CPACK_PROJECT_CONFIG_FILE
AFAIK you cannot (re)write install rule because they have already been
processed.
What you could do (as a workaround) in your CMakeLists.txt is to define
both WinXX specific CPack components
and your "generic" CPack components that can be used as a default.
install(TARGETS foo
EXPORT ${MY_TARGETS_NAME}
RUNTIME DESTINATION ${MY_INSTALL_BIN_DIR} COMPONENT Applications
LIBRARY DESTINATION ${MY_INSTALL_LIB_DIR} COMPONENT Libraries
INCLUDES DESTINATION ${MY_INSTALL_INCLUDE_DIR}
ARCHIVE DESTINATION ${MY_INSTALL_LIB_DIR} COMPONENT DebugDevel
)
install(TARGETS foo
EXPORT ${MY_TARGETS_NAME}
RUNTIME DESTINATION ${MY_WINXX_INSTALL_BIN_DIR} COMPONENT
Applications-Winxx
LIBRARY DESTINATION ${MY_WINXX_INSTALL_LIB_DIR} COMPONENT Libraries-Winxx
INCLUDES DESTINATION ${MY_WINXX_INSTALL_INCLUDE_DIR}
ARCHIVE DESTINATION ${MY_WINXX_INSTALL_LIB_DIR} COMPONENT DebugDevel-Winxx
)
i.e. install the same thing twice in two places.
and then at CPack time (when CPack runs) code some logic in your CPack
Config file in order
to set CPACK_COMPONENTS_ALL to appropriate value depending on the value of
https://cmake.org/cmake/help/v3.14/module/CPack.html#variable:CPACK_GENERATOR
something like
if ("${CPACK_GENERATOR}" STREQUAL "NuGet")
set(CPACK_COMPONENTS_ALL
"Applications-Winxx;Libraries-Winxx;DebugDevel-Winxx")
else()
set(CPACK_COMPONENTS_ALL "Applications;Libraries;DebugDevel")
endif()
that way CPack depending on the generator will ship either "WinXX"
component or "generic" ones.
I think (not tested) it should work but this is clearly a workaround.
