CMake Fails In Cygwin

[bambams]

I'm not sure if this is a cmake version issue or a Cygwin compatibility issue.

(Without -DCMAKE_LEGACY_CYGWIN_WIN32 you are warned also about WIN32 not being defined for Cygwin anymore, but both ways it fails at the same point)

$ cmake --version
cmake version 3.1.2

CMake suite maintained and supported by Kitware (kitware.com/cmake).
$ cmake -DCMAKE_LEGACY_CYGWIN_WIN32=1 -DCMAKE_INSTALL_PREFIX="$HOME" .

There don't appear to be any actual failures in CMakeOutput.log... At least, :set ic | /error has no matches and I don't see anything else that indicates failures...

As far as I can tell from the error INSTALL_LIB_DIR is empty for some
reason. The error is not very descriptive, but gives a line in the
CMakeFile at least.

Maybe try to give it an explicit value via
-DINSTALL_LIB_DIR=$path_where_the_library_should_be_installed.

That is what I thought too, but it doesn't seem to be the case:
