6070	Incorrect warning during compilation of model with external component	Anton.Soppelsa@eurac.edu	Adrian Pop	"Dear all,

during compilation of a model using an external library (dll) on Windows. I receive incorrect warnings about the library be missing from any one of the reported folders. The point is that:

1. The library is not missing;
2. Compilation completes correctly.

It would be better not to receive the warning because it can mislead the user when debugging.

In fact, this is the last part of the reported output:
{{{

post-optimization done.

but the library path is indeed:
{{{
C:\Development\shc-controls\SHCLib\C-Cpp\Cpp-ModelicaInterface\Build\Release\win64\TSModel-Interface.dll
}}}

Moreover, some paths are printed with an extra slash at the beginning.

I do hope this is useful.
