How to add wxWidgets to project via cmake? - cmake

Question

So I am using clion, trying to build a project with wxwidgets. But I get this error:
CMake Error at C:/Program Files/JetBrains/CLion 2020.1/bin/cmake/win/share/cmake-3.16/Modules/FindPackageHandleStandardArgs.cmake:146 (message):
Could NOT find wxWidgets (missing: wxWidgets_LIBRARIES
wxWidgets_INCLUDE_DIRS core)
Here is my cmake file:
cmake_minimum_required(VERSION 3.16)
project(BedrockFinderCpp)
set(wxWidgets_ROOT_DIR <c:/Program Files/wxWidgets-3.1.4>)
set(wxWidgets_CONFIGURATION mswu)
find_package(wxWidgets REQUIRED COMPONENTS core)
include(${wxWidgets_USE_FILE})
find_package(OpenCL REQUIRED)
add_executable(${PROJECT_NAME}
BFFApp.cpp
BFFGui.cpp
PrecomputedRandAdvance.cpp
)
target_include_directories(${PROJECT_NAME} PRIVATE ${OpenCL_INCLUDE_DIRS})
target_link_libraries(${PROJECT_NAME} ${wxWidgets_LIBRARIES} ${OpenCL_LIBRARIES})

Answer 1

I found a "fix" by myself. It can be done with this code:
NOTE: wxWidgets is a subdirectory that contains files from the wxWidgets-3.1.4 directory
cmake_minimum_required(VERSION 3.16)
project(BedrockFinderCpp)
add_subdirectory(wxWidgets)
find_package(OpenCL REQUIRED)
add_executable(${PROJECT_NAME}
BFFApp.cpp
BFFGui.cpp
PrecomputedRandAdvance.cpp
)
target_include_directories(${PROJECT_NAME} PRIVATE ${OpenCL_INCLUDE_DIRS})
target_link_libraries(${PROJECT_NAME} wx::core ${OpenCL_LIBRARIES})
