For debug builds we link the against the release mode libs
for C based libraries, which are technically linked against
a different CRT, which the linker will implicitly try to link.
Which results in a linker warning about mixing the debug/release CRT.
This patch prevents the implicit linking of the release
CRT in debug configurations for sub projects that had issues
with it.
Casting a 64 bit pointer to a 32 bit DWORD gave 2 warnings.
Solved by storing the actual DWORD in the registry table.
Would have preferred to use a union, but C++ doesn't let you
initialize anything other than the first field, and C99 style
initializers are not supported until C++20, so this solution
will have to do until then.
Previously this was done in the deps builder due to the fact we needed
both 32 and 64 bit versions of this dll and CMAKE does not support that
in a single build folder. Now that 32 bit support has been dropped, this
can be safely moved into the codebase.
