how to use src/cmake.mk ?

[starius]

cmake.mk seems to be a native cmake.

1. Why is it needed? Native cmake is already a dependency of MXE.
2. What means "optional" (bfe1525 and 8ff8097). How to build it?

It's mostly (only?) used on OSX to provide a buffer between the update frequency of MacPorts/Homebrew/OSX/Xcode and Debian stable. Using a known toolchain helps greatly when trying to isolate build breakages.

It's optional since it won't be built by default - still experimental in the sense that it's a works-for-me workaround for the larger issue of cross-platform support.

To build native cmake alone:

make cmake MXE_TARGETS=`./ext/config.guess`

to build all the optional native tools:

make build-requirements

and to make them available in your current session:

export PATH=`pwd`/usr/`ext/config.guess`/bin:$PATH
# or
source tools/mxe-activate
