Tests fail in CTest but pass in QtCreator - c++

Question

I am trying to set up a simple Qt project with a unit test (written in QTest) using CMake in Windows.
I can compile the project without problem and execute the test inside Qt Creator.
The problem comes when I try to run the test using CTest (ctest -C Release --output-on-failure --test-dir C:\SRC\MyTests\Test_SO\build), as it ends in failure (exit code 0xc0000135).
How can I make the tests to pass in CTest like they do in Qt Creator?
If possible, I'd like to avoid having to copy all DLLs needed to the executable folder.
Test output
Qt Creator
CTest
Internal ctest changing into directory: C:/SRC/MyTests/Test_SO/build
Test project C:/SRC/MyTests/Test_SO/build
Start 1: tst_MyTest
1/1 Test #1: tst_MyTest .......................Exit code 0xc0000135
***Exception: 0.02 sec
0% tests passed, 1 tests failed out of 1
Total Test time (real) = 0.02 sec
The following tests FAILED:
1 - tst_MyTest (Exit code 0xc0000135
)
Things tried
Tell CTest to use Qt's installation dir as working directory: --build-run-dir C:\Qt\5.12.10\msvc2017_64\bin
Add Qt's installation directory to the Windows path in the main CMake file:
set(CUSTOM_PATH "${CMAKE_BASE_DIR}/bin;$ENV{PATH}")
cmake_path(CONVERT "${CUSTOM_PATH}" TO_NATIVE_PATH_LIST CUSTOM_PATH NORMALIZE)
string(REPLACE ";" "\\;" CUSTOM_PATH "${CUSTOM_PATH}")
set(ENV{PATH} "${CUSTOM_PATH}")
Set the ENVIRONMENT property directly at test level:
list(APPEND QT_DLL_PATH "${QT_BASE_DIR}/bin")
cmake_path(APPEND_STRING QT_DLL_PATH ";$ENV{PATH}")
cmake_path(CONVERT "${QT_DLL_PATH}" TO_NATIVE_PATH_LIST QT_DLL_PATH NORMALIZE)
string(REPLACE ";" "\\;" QT_DLL_PATH "${QT_DLL_PATH}")
add_test(NAME "${TEST_EXECUTABLE_NAME}" COMMAND "${TEST_EXECUTABLE_NAME}" WORKING_DIRECTORY "${QT_DLL_PATH}")
set_tests_properties("${TEST_EXECUTABLE_NAME}" PROPERTIES ENVIRONMENT "PATH=${QT_DLL_PATH}")
