Did you install Ninja? I think that means that Ninja wasn't found in your $PATH.

I have got ninja from here (https://ninja-build.org/), don't know how to install it, as I click on the file, it comes for a second and then disappeared, it means installed? thanks

[sas]

You can follow the instructions here: https://www.java.com/en/download/help/path.xml to add the folder where ninja is located to your $PATH.

I have the same problem. I downloaded ninja.exe file form here https://github.com/ninja-build/ninja/releases . I put into folder "C:\projects\ninja", I added that path into PATH variable, and it still tells CMake Error: CMake was unable to find a build program corresponding to "Ninja". CMAKE_MAKE_PROGRAM is not set. and it is the same as before

[sas]

Can you provide the version of cmake you have installed, where you downloaded it from, and the full contents of your $PATH variable?

well, this is interesting. I did absolutely no changes since I sent this post, I only restarted computer, and now it's working. I don't understand it, but thank you, anyway

[sas]

Ah. Yes. You are supposed to re-login to your account after changing these variables to make sure they are applied to all processes. Restarting had the same effect.

Sorry I didn't think about mentioning this earlier.

Does everything work well now?

Never mind, I will remember it for the next time. Everything works now, problem solved, thanks for your help

@sas Hi I already restarted still get the same problem. What to do?

I tried

C:\> ninja --version

in the CMD and it says:

'ninja' is not recognized as an internal or external command, operable program or batch file.

Me too. I installed jenkins then got this error. After restarting computer, everything's ok :)

[sas]

@chaine09: I suppose you didn't add the directory where ninja.exe is located to your %PATH%. Try adding the correct directory to your path and restarting your host.

[ivanzhovannik]

I firstly added myPath/ninja/bin to PATH instead of adding myPath/ninja. After I did the last option ninja worked.

I'm having same problem on Windows. Does anyone know how to use CMake with ninja on Windows?

I have MacOS Catalina, Cmake, Ninja and QtCreator installed with the following versions and paths:

[@bin]$ sw_vers -productVersion
10.15.6
[@bin]$ which cmake
/usr/local/bin/cmake
[@bin]$ cmake --version
cmake version 3.18.2
CMake suite maintained and supported by Kitware (kitware.com/cmake).
[@bin]$ which ninja
/usr/local/bin/ninja

I'm trying to build a project with QT creator using Cmake. However, the following message appears in QT Creator

As indicated on several websites (such as this SO question I tried the following command but it didn't work:

[@bin]$ ln -s /usr/bin/ninja /usr/bin/ninja-build
ln: /usr/bin/ninja-build: Operation not permitted

I tried also tried the following:

[@bin]$ sudo /usr/bin/ninja-build
