How to create Project using CMake in Qt creator

Hi ,

I am trying to create project by selecting Cmake from drop down but it is not configured i have added Cmake through manage kits how can i configure this.

Getting fallowing error
Running C:\Program Files\CMake\bin\cmake.exe C:/Users/s28194/Documents/sample "-GCodeBlocks - Ninja" in C:\Users\s28194\Documents\build-sample-Desktop_Qt_5_14_0_MinGW_64_bit-Release.
CMake Error: CMake was unable to find a build program corresponding to "Ninja". CMAKE_MAKE_PROGRAM is not set. You probably need to select a different build tool.
-- Configuring incomplete, errors occurred!

Also tried to install Ninja https://github.com/ninja-build/ninja/releases that also did not help me.

Please someone guide me how can i solve this.

@sush123 Did you try to define CMAKE_MAKE_PROGRAM so it points to make from MinGW?

sush123 · 17 Jan 2020, 11:14

yes i do have MinGW

@sush123 That's not what I mean.
You should try to set CMAKE_MAKE_PROGRAM, so it points to make executable from MinGW.
In QtCreator you can do it in Projects/YOUR_KIT/Build/CMake and then add this variable (or edit when already there) and set whole path to make from MinGW.

@sush123 Did you follow the step described in documentation?

I'm not sure why it doesn't find your version of ninja. Did you restart QtCreator after installing Ninja? Make sure your CMake Generator is set properly. Tools->Kits->(Select your Kit)->CMake generator (towards the bottom). You could try switching your Generator to 'MinGW Makefiles'.

Can anyone help me to find Ninja setup to install.
I tried using below link but it is disappearing after double clicking on setup file not sure why,
https://github.com/ninja-build/ninja/releases

@sush123 Do you really need Ninja? Make (which is part of MinGW) can compile several files in parallel.

sush123 · 20 Jan 2020, 08:56

i am not sure really need ninja or not but not able to narrow down a reason for getting error like
" CMake Error: CMake was unable to find a build program corresponding to "Ninja". CMAKE_MAKE_PROGRAM is not set. You probably need to select a different build tool.
-- Configuring incomplete, errors occurred!?"

After setting CMAKE_MAKE_PROGRAM, this as well

How, when and where did you set it?

sush123 · 20 Jan 2020, 12:29

Created new sample project by selecting :
Application -> Qt Widgets Application ->build system (Cmake) in dropdown->Checked Desktop Qt 5.14.0 MinGW 64-bit.

I can see project created in Qt creator which is not configured warning symbol before project name.

@sush123 You need to set CMAKE_MAKE_PROGRAM in your projects Build settings: "Projects/Build & Run/YOUR_KIT/Build/CMake"

sush123 · 21 Jan 2020, 06:08

Yes i did that then it changed warning symbol into folder kind but then still i am getting this error :

See also "C:/Users/s28194/Documents/build-untitled4-Desktop_Qt_5_14_0_MinGW_64_bit-Debug/CMakeFiles/CMakeOutput.log".

Also Build and run icons are disabled.

@sush123 You should not pass -GNinja to CMake

Other possibility would be to install Ninja and add the path to it to PATH in your projects Build settings.

sush123 · 21 Jan 2020, 06:16

i tried adding ninja exe path under manage kits -> Cmake -> under manual i added "pathtofindninja",
Still no changes,
i could see error symbol with "Invalid codemodel file generated by Cmake " message under projects -> Build settings

kits -> Cmake

This is for CMake and not Ninja!
Please add the path containing ninja.exe to PATH in your projects Build settings.

PATH in

im really not finding where excatly i should add this ninja exe path in project settings.

@sush123 "Projects/Build & Run/YOUR_KIT/Build/Build Environment" - edit PATH variable here (append directory containing ninja.exe).

sush123 · 21 Jan 2020, 10:04

i did append path C:\Qt\Qt5.14.0\Tools\mingw730_64\bin;C:\Users\s28194\Documents\ninja.exe;C:\Users\s28194\AppData\Local\Microsoft\WindowsApps;

still i have disabled icons for build and run at left bottom.

This is wrong. In PATH you only add directories, so:

 C:\Qt\Qt5.14.0\Tools\mingw730_64\bin;C:\Users\s28194\Documents
