Cmake Could not find wxWigets - windows

Question

I want to compile a source code on windows using CMake, it uses wxWigets library.
I downloaded the wxWigets from the page: https://www.wxwidgets.org/
After building by Visual Studio, I got the library /lib file.
I have already set PATH for wxWidgets_LIBRARIES and wxWidgets_INCLUDE_DIRS. But the following errors cannot be resolved.
CMake Error at C:/Program Files/CMake/share/cmake-3.11/Modules/FindPackageHandleStandardArgs.cmake:137 (message):
Could NOT find wxWidgets (missing: wxWidgets_LIBRARIES
wxWidgets_INCLUDE_DIRS)
Call Stack (most recent call first):
C:/Program Files/CMake/share/cmake-3.11/Modules/FindPackageHandleStandardArgs.cmake:378 (_FPHSA_FAILURE_MESSAGE)
C:/Program Files/CMake/share/cmake-3.11/Modules/FindwxWidgets.cmake:953 (find_package_handle_standard_args)
CMakeLists.txt:52 (find_package)
I also read the thread about this problem in: CMake could not find wxWidgets on Windows
But there is no solution for my case.

Answer 1

You may specify wxWidgets_ROOT_DIR variable to point to your wxWidgets installation.
As far as I understand, you may set either CMake variable via -D option to cmake:
cmake -DwxWidgets_ROOT_DIR:PATH=D:/path/to/wxWidgets/ ...
or you may set environment variable
set wxWidgets_ROOT_DIR=D:\path\to\wxWidgets\ ...
(Note that CMake path variables use "universal" directory separator '/', but environment variables use native directory separator, '\' for Windows).
This variable is described in documentation for FindwxWidget.
Using wxWidgets_LIB_DIR variable could be tricky, see that question.

Answer 2

I have a solution witch can solve this problem.
there is something wrong with the FindwxWidgets.cmake File
Firstly, delete the file
C:/Program Files/CMake/share/cmake-3.11/Modules/FindwxWidgets.cmake
instead, you can find the package by using wxWidetsConfig.cmake file
YOUR_PATH\wxWidgets\lib\cmake\wxWidgets\wxWidgetsConfig.cmake.
add the flowing codes in your CMakeLists.txt and you can use wxWidgets
# set(CMAKE_PREFIX_PATH C:/dev/wxWidgets) also works
set(CMAKE_PREFIX_PATH C:/dev/wxWidgets/lib/cmake/wxWidgets)
find_package(wxWidgets COMPONENTS core base REQUIRED)
add_executable(wxwdemo WIN32 main.cpp)
target_link_libraries(wxwdemo ${wxWidgets_LIBRARIES})
target_include_directories(wxwdemo PUBLIC ${wxWidgets_INCLUDE_DIRS})
then it works
