Add version resource to Windows shared library DLL

[ahuj9]

Description

Open62541 when built as a shared library on Windows could use a version resource .rc file configured from ${OPEN62541_VER_X} CMake variables.

Sounds good. Where should this be installed?

The easy way is to add this, this and this to tools/cmake. Then in the CMakeLists.txt you should add:

generate_product_version(
    open62541_resource_version
    NAME "open62541"
    VERSION_MAJOR ${OPEN62541_VER_MAJOR}
    VERSION_MINOR $OPEN62541_VER_MINOR}
    VERSION_PATCH ${OPEN62541_VER_PATCH}
    VERSION_REVISION ${OPEN62541_VER_LABEL}
)

This generates variable open62541_resource_version to add into the add_library command:

add_library(open62541 ... ${open62541_resource_version})

For Windows, metadata is embedded into the DLL, so, no installation is needed.

It is not necessary to make it so complicated with macros and different files. A simple template and configure_file is completely sufficient.
