cygcheck is for cygwin packages. So you are creating a cygwin packaage and then checking?

But I'm interested in a check after 'make all'.

How is that supporsed to work? ldd is able to find the dll - but its not visible at runtime?

I see you are using cmake build - and thats creating cygpetsc.dll.

Will have to see how this can be added to all-legacy and all-gnu.

But it still doesn't work for me. [with cmake build]
