[CMake] make_directory deprecated. What's the correct solution to generate directories at build time now?

[Paulo Waelkens]

Hello,

to create a cmake directory *at build time* (
http://stackoverflow.com/questions/3702115/creating-a-directory-in-cmake)
you could use

add_custom_target(build-time-make-directory ALL
COMMAND ${CMAKE_COMMAND} -E make_directory ${directory})

*"make_directory"* is now listed as deprecated in the new cmake
documentation (https://cmake.org/cmake/help/v3.6/command/make_directory.html
).

How exactly could I repeat the original behaviour without using deprecated
functionality?
I understand that I'm supposed to use *file(MAKE_DIRECTORY ${directory})*
somehow, but don't understand how exactly to connect this with COMMAND.

I've tried to use
*COMMAND ${CMAKE_COMMAND} -E file ... *(definitely wrong, because
cmake.exe -E <command> [args...] does not list "file" as an available
command)
*COMMAND file(MAKE_DIRECTORY ${directory})* (wrong, again, *'file' is not
recognized as an internal or external command*)

Does anyone know how to do this right? I'll keep using the deprecated stuff
for now, but that's kind of sad.

Thanks for the help! Cheers,
Paulo

You are right!

The documentation quick search for the "make_directory" keyword does not
find the cmake executable documentation (i.e. the make_directory
command-line tool), only the script command. That tripped me up.
If you manually go to the cmake executable documentation (
https://cmake.org/cmake/help/v3.6/manual/cmake.1.html), you'll find that
"cmake.exe -E make_directory..." is indeed still up to date

Thanks Iosif! Cheers,
Paulo

I think only the cmake script command make_directory is deprecated, not
the cmake command-line tool -E mode make_directory?
