How to create Project using CMake in Qt creator

mchinand

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.

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

After setting CMAKE_MAKE_PROGRAM

How, when and where did you set it?

sush123

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.

jsulm

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

sush123

Yes i did that then it changed warning symbol into folder kind but then still i am getting this error :
Running C:\Program Files\CMake\bin\cmake.exe C:/Users/s28194/Documents/untitled4 "-GCodeBlocks - Ninja" in C:\Users\s28194\Documents\build-untitled4-Desktop_Qt_5_14_0_MinGW_64_bit-Debug.
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!
See also "C:/Users/s28194/Documents/build-untitled4-Desktop_Qt_5_14_0_MinGW_64_bit-Debug/CMakeFiles/CMakeOutput.log".
CMake process exited with exit code 1.

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

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.

jsulm

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

sush123

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.

C:\Users\s28194\Documents\ninja.exe

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

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

sush123

thank you so much it configured

jsulm

@sush123 Great I could help! :-)
