build option disabled and greyed out

jcren

I installed Qt5.12.4 and qtcreator-4.9.2 in my ubuntu 16.04. I have installed it successfully several times before. But this time, after installation ,I found out the build option disabled and greyed out, which you can see in the picture below:

I do not know how to fix it. I have searched online (including on this forum) but did not find solutions. Could anyone help me with this? Thanks in advance.

Hi,

Did you check your kits ?

@SGaist Thank you for your reply. I just checked kits and add cmake path in it. Now it can work. Thank you very much.
