Converting a meson.build library to CMakeLists - cmake

Question

So, one of my uni courses uses a meson.build system for one of the libraries we have to use.
The library is organized like
this
Now, using CLion, I have trouble linking to that library. Earlier I have been trying cloning it, and setting target_include_directories to the src and includefolders.
For some reason that didn't do the trick, and I'm now trying to convert the meson.build file to a CMakeFiles which I can just add/compile.
The file looks like:
project('animationwindow', ['c', 'cpp'], version: '0.01', default_options: ['cpp_std=c++17', 'default_library=static', 'buildtype=debugoptimized'])
if host_machine.system() == 'windows'
sdl2_dep = subproject('sdl2_windows').get_variable('sdl2_windows_dep')
sdl2image_dep = subproject('sdl2_image_windows').get_variable('sdl2_image_windows_dep')
else
sdl2_dep = dependency('sdl2')
sdl2image_dep = dependency('sdl2_image')
endif
build_files = [
'src/internal/FontCache.cpp',
'src/internal/KeyboardKeyConverter.cpp',
'src/internal/nuklear_implementation.cpp',
'src/widgets/Button.cpp',
'src/widgets/TextInput.cpp',
'src/widgets/DropdownList.cpp',
'src/AnimationWindow.cpp',
'src/Color.cpp',
'src/Image.cpp',
'src/Widget.cpp']
incdir = include_directories('include')
animationwindow = static_library('animationwindow', build_files, include_directories: incdir, dependencies: [sdl2_dep, sdl2image_dep], install: true)
install_subdir('include', install_dir: '.')
install_subdir('src', install_dir: '.')
animationwindow_dep = declare_dependency(link_with: animationwindow, include_directories: incdir)
import('pkgconfig').generate(animationwindow)
# ex = executable('prog', 'src/test.cpp', include_directories: incdir, dependencies: [sdl2_dep, imgui_dep], link_with: animationwindow)
I have converted that to:
cmake_minimum_required(VERSION 3.16)
project(animationwindow)
set(CMAKE_CXX_STANDARD 17)
find_package(SDL2 REQUIRED)
add_executable(
animationwindow
src/internal/FontCache.cpp
src/internal/KeyboardKeyConverter.cpp
src/internal/nuklear_implementation.cpp
src/widgets/TextInput.cpp
src/widgets/Button.cpp
src/widgets/DropdownList.cpp
src/AnimationWindow.cpp
src/Color.cpp
src/Image.cpp
src/Widget.cpp
)
include_directories(animationwindow include)
The question now is, how do I link this from the main file. Can I just somehow link the CMakeLists, or do I have to precomile the library and then somehow add it?
