Can't compile project using CLion and CMake

Using MaintenanceTool.exe I also don't see separate components for MSVC
You should. You could try to reinstall Qt.

Indeed, it has now been possible to install the MSVC version. I have upgraded CMake, but this has not corrected the bugs in the project build:2>main.obj : error LNK2019: unresolved external symbol "__declspec(dllimport) public: __cdecl QString::~QString(void)" (__imp_??1QString@@QEAA@XZ) referenced in function main 2>main.obj : error LNK2019: unresolved external symbol "__declspec(dllimport) public: __cdecl QString::QString(char const *)" (__imp_??0QString@@QEAA@PEBD@Z) referenced in function main 2>main.obj : error LNK2019: unresolved external symbol "__declspec(dllimport) public: __cdecl QApplication::QApplication(int &,char * *,int)" (__imp_??0QApplication@@QEAA@AEAHPEAPEADH@Z) referenced in function main 2>main.obj : error LNK2019: unresolved external symbol "__declspec(dllimport) public: virtual __cdecl QApplication::~QApplication(void)" (__imp_??1QApplication@@UEAA@XZ) referenced in function main 2>main.obj : error LNK2019: unresolved external symbol "__declspec(dllimport) public: static int __cdecl QApplication::exec(void)" (__imp_?exec@QApplication@@SAHXZ) referenced in function main 2>main.obj : error LNK2019: unresolved external symbol "__declspec(dllimport) public: void __cdecl QWidget::show(void)" (__imp_?show@QWidget@@QEAAXXZ) referenced in function main 2>main.obj : error LNK2019: unresolved external symbol "__declspec(dllimport) public: void __cdecl QWidget::resize(int,int)" (__imp_?resize@QWidget@@QEAAXHH@Z) referenced in function main 2>main.obj : error LNK2019: unresolved external symbol "__declspec(dllimport) public: __cdecl QPushButton::QPushButton(class QString const &,class QWidget *)" (__imp_??0QPushButton@@QEAA@AEBVQString@@PEAVQWidget@@@Z) referenced in function main 2>main.obj : error LNK2019: unresolved external symbol "__declspec(dllimport) public: virtual __cdecl QPushButton::~QPushButton(void)" (__imp_??1QPushButton@@UEAA@XZ) referenced in function main 2>main.obj : error LNK2001: unresolved external symbol "public: virtual __cdecl QApplication::~QApplication(void)" (??1QApplication@@UEAA@XZ) 2>main.obj : error LNK2001: unresolved external symbol "public: virtual __cdecl QPushButton::~QPushButton(void)" (??1QPushButton@@UEAA@XZ) 2>main.obj : error LNK2001: unresolved external symbol "public: __cdecl QString::~QString(void)" (??1QString@@QEAA@XZ) 2>D:\QSnake\RelWithDebInfo\QSnake.exe : fatal error LNK1120: 12 unresolved externals -

And make sure that the msvc libs are used during linking.
-
Maybe I should add project additional include directories?

How can I check it? I guess I have default settings, because I didn't change them.
P.S. Maybe you know, after how many messages can I post more than once in 10 minutes?

Since you've a msvc project take a look in the linker options. Or use cmake-gui to see the CMake values.

@Christian-Ehrlicher If I correctly understood you, I use MSVC linker:
CMAKE_LINKER - C:/Program Files (x86)/Microsoft Visual Studio/2019/Community/VC/Tools/MSVC/14.28.29910/bin/Hostx64/x64/link.exe -
I don't care about the linker but about the input for it - do you link against the QtWidget dll for msvc?
-
Finally solved the problem... The reason turned out to be very stupid - CMake was not specified by MSVC, but by MinGW library and the wrong solution was generated.
However, in debug version still does not work (now builds only in release) because dll files with suffix "d" are not included. Should they be installed as separate components? They’re not in the bin directory where exist release dlls. -
@mingvv mingw bin directory is having both release and debug version (with d suffix) of dlls.

Thank you for the answer!
Did you install them separately (I mean, there is a separate item in the installer? If so, what is it called?)? -

Do you mean release and debug? No, those are both installed by default.

Yes. I reinstalled Qt, but debug files never appeared for MinGW (with MSVC all OK). "Qt Debug Information" is not that?

That's strange. On my machine I have both. How did you install Qt and what version?

Using Qt Online Installer for Windows I installed the default set for Qt 6 as well as an additional component for MSVC.
What I have now (as it looks in MaintenanceTool):
*) Qt -> Qt 6.0.2 -> MSVC 2019 64-bit
*) Qt -> Qt 6.0.2 -> MinGW 8.1.0 64-bit
*) Qt -> Developer and Designer Tool -> Qt Creator 4.14.1 CDB Debugger Support
*) Qt -> Developer and Designer Tool -> Debugging Tools for Windows
*) Qt -> Developer and Designer Tool -> MinGW 8.1.0 64-bit
*) Qt -> Developer and Designer Tool -> CMake 3.19.2 64-bit
*) Qt -> Developer and Designer Tool -> Ninja 1.10.0 -

@mingvv I did not yet install Qt6, maybe something is different there.
You’re using version 5? Honestly, I don’t know why I put 6. I decided that the new and apparently more active development of it. Are there any significant differences? Otherwise, I would have reassigned to 5.

Yes, currently not all Qt modules are available in Qt6 and will be added in later Qt6 releases. It is save to stay with Qt5 for now.

I reinstalled to version 5. Still debug dlls are only for MSVC... Are you sure there’s no need to add an extra component in installer or something else? Otherwise I don’t know what it is and why it don't install debug libraries for MinGW.
