wxWidgets from mingw-w64 can't be used in CLion

Question

i can build wxwidgets 3.1.6 by mingw32 and used in CLion or CodeBlock on Windows.

but when i use mingw-w64 to compiled wxwidgets lib on new computer, it will work well in codeblock, but it will not be able to use lib in CLion. I always receive the following message:

and more

this msg look like unsuccessful use of lib, but there is no mention of "cannot find lib" in clion. I read many articles, they all show that this is related to c++11, but I use C++14.

The following is the shell I built wxwidgets in wxWidgets_3.1.6/build/msw:

mingw32-make -f makefile.gcc clean
mingw32-make -f makefile.gcc BUILD=debug SHARE=0 MONOLITHIC=1 UNICODE=1
mingw32-make -f makefile.gcc BUILD=release SHARE=0 MONOLITHIC=1 UNICODE=1

what did I miss?

Perhaps you don't set some required variables in the CMakeLists.txt.

I don't need own compiled wxWidgets libs, but all it works "out of box" with the downloaded binaries from official website https://www.wxwidgets.org/downloads#v3.1.5_msw -> "MinGW-w64 8.1", "Header Files" ("include" folder), "64-Bit (x86_64)" "Development Files" ("lib" folder).

My CMakeLists.txt

cmake_minimum_required(VERSION 3.21)
project(temp)

set(CMAKE_CXX_STANDARD 14)

aux_source_directory(. SRC_LIST)

set(wxWidgets_ROOT_DIR "../../../wxWidgets-3.1.5/")
set(wxWidgets_LIB_DIR "${wxWidgets_ROOT_DIR}lib/gcc810_x64_dll")
set(wxWidgets_LIBRARIES "${wxWidgets_ROOT_DIR}lib")
set(wxWidgets_INCLUDE_DIRS "${wxWidgets_ROOT_DIR}include")

if(CMAKE_BUILD_TYPE STREQUAL "Debug")
    set(wxWidgets_CONFIGURATION mswud)
endif()
if(CMAKE_BUILD_TYPE STREQUAL "Release")
    set(wxWidgets_CONFIGURATION mswu)
endif()
find_package(wxWidgets COMPONENTS core base REQUIRED)
include(${wxWidgets_USE_FILE})

add_executable(${PROJECT_NAME} ${SRC_LIST})
target_link_libraries(${PROJECT_NAME} ${wxWidgets_LIBRARIES})
