A linker linker error when building libraries that are linked/added to the project that reside is a path with whitespaces.

For example:

In the errors above, the libraries in question are in a directory:
C:\Users\xxxxxxx\Desktop\Folder Space\src\Libs

The path is passed to the Linker as:
C:/Users/xxxxxxx/Desktop/Folder\ Space/src/Libs

Note the '\' character added after "Folder" and before "Space", likely an escape character.

Instead, the path likely just needs to be passed in quotes, without the escape character

Note that this issue only affects linking. There are no issue compiling source files in the same directory.
