      When just creating a CMake based project, the Build command is inaccessible. Messages output looks like this:

      Running "/usr/bin/cmake /home/max/proj/cmaketest '-GCodeBlocks - Ninja' -DCMAKE_CXX_COMPILER:STRING=/usr/bin/clang++ -DCMAKE_C_COMPILER:STRING=/usr/bin/clang" in /tmp/QtCreator-8vsTtb/qtc-cmake-XXuvkiUU.

      Only when I manually click "Run CMake" once again, the button is unblocked. More messages added:

       Running "/usr/bin/cmake /home/max/proj/cmaketest '-GCodeBlocks - Ninja'" in /tmp/QtCreator-8vsTtb/qtc-cmake-XXY0KLpE.

      When I press Build, it runs CMake yet once again. This is a problem on its own, since some complex CMake projects dealing with dynamically generated dependencies may take significant time to configure (up to minutes).

      What's worse is, Creator shows build error:

      10:24:55: Running steps for project cmaketest...
10:24:55: Persisting CMake state...
Error while building/deploying project cmaketest (kit: Clang)
When executing step "CMake Build"
10:24:55: Elapsed time: 00:00.

      Though, the build has actually been triggered and runs in the background. The Build button is then once again disabled. If I "Run Cmake" yet again, it starts rebuilding normally.
