Static Compilation for wxWidgets C++

As a starter I would like to point out that I have spent few hours trying to resolve the problem with no success. I wrote a small project using wxWidgets library for C++ in Clion on Mac. Since majority of my classmates have done their projects in VisualStudio on Windows, nobody could help me out. The project must be handed in in a form of an executable which will work on any computer. I suppose that the solution I should be looking for is static compilation which would staticly link all of the libraries to the executable file. I tried adding some flags like the one below to the Cmake:

set(CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} -lpthread")

but it did not help whatsoever. I have absolutely no knowledge on how CMake works and I would greatly appreciate any help.

The whole cmake file which I currently have:

cmake_minimum_required(VERSION 3.9)
project(Lab3)
set(EXECUTABLE_NAME "Indexer")


set(CMAKE_CXX_STANDARD 11)
set(CMAKE_CXX_FLAGS_RELEASE "-O2 -DNDEBUG")
set(CMAKE_CXX_FLAGS_DEBUG "-g -Wall -Wextra -DWX_PRECOMP")

# set(CMAKE_RUNTIME_OUTPUT_DIRECTORY ${CMAKE_SOURCE_DIR}/bin)

find_package(wxWidgets COMPONENTS core base REQUIRED)

include(${wxWidgets_USE_FILE})
include_directories(include/ ${wxWidgets_INCLUDE_DIRS})

file(GLOB SOURCES "src/*.cpp")
add_executable(${PROJECT_NAME} main.cpp Source.cpp Source.h)

target_link_libraries(${PROJECT_NAME} ${wxWidgets_LIBRARIES})

EDIT: I guess I didn't specify the problem clearly enough. The program compiles fine- everything works. It's just that whenever I try to copy the executable file (the end application) to a different computer it just doesn't work or shows up as a text file with corrupted characters instead of an application with a GUI etc..

To build wxWidgets with as few dependencies as possible, you should configure it with not only --disable-shared, but also --disable-sys-libs, to prevent it from using any third party libraries (e.g. libz, libpng, ...) that might be installed on your system.

After building your application using wxWidgets, you should confirm that otool -L YourApp.app/Contents/MacOS/YourApp doesn't show any non-system libraries.

You're not copying the right thing across. What you believe to be the application is probably just some kind of launcher.

Mac GUI applications do not consist of just a single file. Your Indexer app is actually what Apple call a bundle. The Finder presents this to the user as a single entity but it's really a folder.

You can look inside a bundle by right-clicking on it (or Ctrl+click) and selecting Show package contents. If you want to understand a bit more about what's in there, Apple document it here.

A good way to get a bundle from A to B might be to ZIP it. Once you have done that you will find out whether your efforts to statically link it have been successful. What I don't know is where your build system has put it, but maybe this post will help. It will be called Indexer.app, maybe Spotlight can find it.
