REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4610 Google Test hides test registration in global constructors on global objects. Global constructors are traditionally implemented by placing references to the global constructor's symbol in special sections (traditionally named .ctors or .init_array). These sections are not explicitly referenced by the linker, and libc only looks at special start and end symbols (and calls them). This works fine if you're linking a program manually using gcc a.o b.o c.o -o test_suite but fails miserably when using static libraries (such as what EDK2 does), because traditional static archive symbol resolution rules don't allow for object files to be pulled in to the link if there isn't an undefined symbol reference to that .o elsewhere. Fix it by passing --whole-archive (GCC) and /WHOLEARCHIVE (MSVC). These options force the linker to pull in the entire static library, thus including previously-unreferenced constructors and making sure multi-file gtest EDK2 components work.
