Building Qt-test with Cmake and Ctest

Question

I recently started exploring unit-testing with QT library, so I just want to repeat simple code from its documentation and build it by Cmake (I have msvc compiler and use CLion IDE).

Cmake:

cmake_minimum_required(VERSION 3.17)
project(unit_tests)
find_package(Qt5Test REQUIRED)

set(CMAKE_INCLUDE_CURRENT_DIR ON)

set(CMAKE_AUTOMOC ON)

enable_testing(true)

add_executable(mytest tst_mytest.cpp)
add_test(mytest mytest)

target_link_libraries(mytest PRIVATE Qt5::Test)

tst_mytest.cpp:

#include <QObject>
#include <QtTest/QTest>
class MyFirstTest: public QObject
{
    Q_OBJECT

private:
    bool myCondition()
    {
        return true;
    }

private slots:
    void initTestCase()
    {
        qDebug("Called before everything else.");
    }

    void myFirstTest()
    {
        QVERIFY(true);
        QCOMPARE(1, 1);
    }

    void mySecondTest()
    {
        QVERIFY(myCondition());
        QVERIFY(1 != 2);
    }

    void cleanupTestCase()
    {
        qDebug("Called after myFirstTest and mySecondTest.");
    }
};
QTEST_MAIN(MyFirstTest)
#include "tst_mytest.moc"

Then, I run All CTest and this test fails with error:

"F:\CLion 2020.3.1\bin\cmake\win\bin\ctest.exe" --extra-verbose

Exception:

The following tests FAILED:
      1 - foo (Exit code 0xc0000135
)
Process finished with exit code 8

For some reason the test is not appropriate for fixture requirements. I had a look for some other Qt-questions and here about structure of unit-tests, but didn`t see a lot of differences with my code. Here are Cmake options. After adding Qt directory to Path environment variable there is a linking error:

CMake Error at CMakeLists.txt:2 (project):
  The CMAKE_C_COMPILER:

    cl

  is not a full path and was not found in the PATH.

  To use the NMake generator with Visual C++, cmake must be run from a shell
  that can use the compiler cl from the command line.  This environment is
  unable to invoke the cl compiler.  To fix this problem, run cmake from the
  Visual Studio Command Prompt (vcvarsall.bat).

  Tell CMake where to find the compiler by setting either the environment
  variable "CC" or the CMake cache entry CMAKE_C_COMPILER to the full path to
  the compiler, or to the compiler name if it is in the PATH.

What is going wrong here?
