If the CPM package names are too long, depending on the path to the
base folder, MSBuild throws the error MSB4023.
Meaning, the path is too long.
This reduces the risk of this happening.

Delay the inclusion of the helper function to after the patch is applied.
Otherwise in the initial CMake run, the unpatched version will be used.
This in turn may lead to issues.

When the source files get added in the same CMakeLists.txt where the
target gets defined, the path to the source files is relative
(If not explicitly done in the CMakeLists.txt).
This patch fixes this issue, as these relative paths are already what is
needed for the folders.

This caused errors in VACore build.
As new compilers support this, it is removed completely.

First, use the CMAKE_RUNTIME_OUTPUT_DIRECTORY variable to get the configuration dependant output folder.
However, configure_file does not support generator expressions.
Thus switch to file(GENERATE).

The Visual studio generator is a multi config generator.
This means, that form one project, e.g debug and release can be build.
This caused issues, as the default behaviour is to append the configuration type to the output directory.
Thus, dlls and required files were not copied to the right locations.

By adding the generator expression '$<Config>' to the CMAKE_RUNTIME_OUTPUT_DIRECTORY path,
the default appending behaviour is supressed and every configuration uses its own output folder.
The dlls and required files can then be copied in the correct folder for each configuration.
