I am compiling CTL-1.4.1 which works on windows (unlike the git head which chokes on a compiler limitation) and OpenEXR 2.2. I run into a problem compiling OpenEXR_CTL 1.0.1. The compilation works, but the linking shows:

1>ImfCtlApplyTransforms.obj : error LNK2019: unresolved external symbol "class IlmThread_2_2::Mutex & __cdecl Ctl::rcPtrMutex(class Ctl::RcObject *)" (?rcPtrMutex@Ctl@@YAAEAVMutex@IlmThread_2_2@@PEAVRcObject@1@@Z) referenced in function "private: void __cdecl Ctl::RcPtr<class Ctl::FunctionArg>::ref(void)" (?ref@?$RcPtr@VFunctionArg@Ctl@@@Ctl@@AEAAXXZ)

1>ImfCtlCopyFunctionArg.obj : error LNK2001: unresolved external symbol "class IlmThread_2_2::Mutex & __cdecl Ctl::rcPtrMutex(class Ctl::RcObject *)" (?rcPtrMutex@Ctl@@YAAEAVMutex@IlmThread_2_2@@PEAVRcObject@1@@Z)

I checked the CtlRcPtr.h/cpp files and the function is defined, but never exported.
Any ideas on how to make this work?
