You can use CMake 3.x on older systems. Write platform checks for specific
C++11 features and implement "old" style code if the C++11 features (e.g.
lambdas) are not available.
Use https://cmake.org/cmake/help/v3.1/prop_gbl/CMAKE_CXX_KNOWN_FEATURES.html
and
Hi Petr.
You're using a feature (`CMAKE_CXX_STANDARD`) introduced in CMake version
3.1, so you should require a minimum version >= that.
You can learn the version of CMake by running `cmake --version`

If I did that nearly nobody would be able to compile my program as
cmake >= 3.1 is extremely rare on most distributions. Even ubuntu's
PPA builder has some ancient version.

Hi Petr,
you can download CMake from https://cmake.org/download/.
There are also prebuilt binaries available.
We use the *.sh files to install CMake on our linux servers.
.) Install CMake to /opt/cmake-3.4.2.
.) Create a symlink to /opt/cmake
.) Create another symlink from the /opt/cmake/bin/*
I think you completely misunderstood me. I know I can install it on my
machine, but I can hardly install it on PC's or servers of users who
use my program.
I want to make it as easy as possible to let users compile my program.
Having to install anything by hand instead of system package manager

Hello,
CMake 3.3.1 is available from my PPA, in case it helps:

By stable you mean Jessie that was recently released and is almost
nowhere in production yet? :)
On my debian server:
$ cmake --version
cmake version 2.8.9
On one of wikimedia's ubuntu servers (the newer ones):
$ cmake --version
cmake version 2.8.12.2
On travis-ci cmake is about 2.8.7 and on
What version of CMake are you using? I’m using 3.3.2. The only other thing I
did was:
set_property(GLOBAL PROPERTY CXX_STANDARD_REQUIRED)
I’m guessing this probably does nothing since it is probably a target property.

Can you elaborate on it a bit?
I put set(CMAKE_CXX_STANDARD 11) as first line of my CMakeLists and it
still doesn't work, without the hack I used I get errors while
compiling.
Can you give me example file in which it works? I guess there is more
needed for it to work.

What do you mean by "target" property? I don't see any target
mentioned there. I don't have this line in there. I don't know which
CMake this is, it failed on server we use for unit tests, but I have
required min. version set to 2.8.7

I have the following two lines in my CMakeLists.txt
set_property(GLOBAL PROPERTY CXX_STANDARD 11)
set_property(GLOBAL PROPERTY CXX_STANDARD_REQUIRED)
However when compiling some of my source files, the -std=c++11 flag is not
added.
Just for good measure I added:
I would also like to know this, right now I do this and it works, but
it produced warnings on MSVC, so I did this nasty patch:
if(WIN32)
if(MINGW)
SET(CMAKE_CXX_FLAGS "-mwindows -std=c++11")
endif()
else()
SET(CMAKE_CXX_FLAGS "-std=c++11")
endif()

Hi,
CXX_STANDARD is a target property, not a global one. You can either set
CXX_STANDARD for every target that needs it, or set it globally by changing
the default value.
You can do the latter by setting the variable CMAKE_CXX_STANDARD before
defining any target that depends on it:
Thanks, setting the global variable solved my issue.
