Summary0011228: CMake does not generate Unix Makefiles compatible with mainline GNU Make on Cygwin
DescriptionI have a project setup for an out of source build. When using CMake to generate a Unix Makefile for my project, the makefiles contain windows paths in the dependency lines for the generated makefiles. This is no longer compatible with the version of GNU Make being compiled for cygwin.

It would be beneficial to change CMake to generate unix paths for the dependencies when generating the Unix Makefile under Cygwin.

You have to use a cygwin built cmake to use the cygwin tool chain. The windows CMake can not be used to create files that work with the cygwin tools. The Unix Makefiles generator is useful for using gmake with MS cl.

That is the scenario we are trying to use. We would like to use CMake to generate makefiles which can be built using GNU Make to invoke the MS cl compiler. In order for this to work, windows paths need to be passed to the cl compiler, however the makefile shouldn't contain windows paths in the dependency statements as the mainline GNU make no longer allows that in the syntax.

Cygwin broke make for this. :)

I have a patched version that I use here:

http://www.cmake.org/files/cygwin/make.exe-cygwin1.7 [^]

Since CMake is a windows program there is no way it can generate cygwin style paths.

The patch for make was pushed into upstream gmake over a year ago, but was never picked up by the cygwin maintainers of gnu make.
