I'm trying to build a CMake project using clang instead of gcc. The
project is cross-platform and builds cleanly on Cygwin with gcc. With
Clang it says:
[ 33%] Built target X
make[4]: *** No rule to make target 'X.dll.a', needed by 'X.exe'. Stop.
CMakeFiles/Makefile2:1140: recipe for target 'tools/CMakeFiles/X/all' failed
I don't know how to fix this, but I'm not completely sure that it's not
my project that instructs CMake to do this (how would I know?).
If not, is there a way to make CMake link directly against the .dll?

Cygwin64 on Windows 10 with CMake 3.3.2
This seems to be caused by the fact that clang command line for building
shared libraries does not receive the "-Wl,--enable-auto-import" option,
which gcc does.
For GCC this seems to happen in Modules/Platform/CYGWIN-GNU.cmake:53,
but I can't figure out where this should be placed to fix it for clang.
Any pointers?
