undefined reference to `kiss_fft_alloc'

Hello,

I modified the CMakeLists.txt inside the src folder to the following so that I can include the header file as a library.

include_directories (${CMAKE_CURRENT_SOURCE_DIR}/src)
include_directories (${CMAKE_CURRENT_SOURCE_DIR}/../libs/kiss_fft130)

add_library (
    Gist STATIC
    AccelerateFFT.cpp
    AccelerateFFT.h
    CoreFrequencyDomainFeatures.cpp
    CoreFrequencyDomainFeatures.h
    CoreTimeDomainFeatures.cpp
    CoreTimeDomainFeatures.h
    Gist.cpp
    Gist.h
    MFCC.cpp
    MFCC.h
    OnsetDetectionFunction.cpp
    OnsetDetectionFunction.h
    WindowFunctions.cpp
    WindowFunctions.h
    Yin.cpp
    Yin.h
)

target_include_directories (${PROJECT_NAME} PUBLIC ${CMAKE_CURRENT_SOURCE_DIR})

source_group (Source src)

target_compile_definitions (Gist PUBLIC -DUSE_KISS_FFT)

This is the CMakeLists.txt in the folder that contains my main function.

add_executable(plot_fourier_transform plot_fourier_transform.cpp)

target_compile_options(plot_fourier_transform PRIVATE)

target_include_directories(plot_fourier_transform
  PRIVATE
    "${CMAKE_CURRENT_SOURCE_DIR}/../../include"
)

target_link_libraries(plot_fourier_transform
  PRIVATE
    AudioFile
    Gist
    Python3::Python
    Python3::NumPy
)

set_target_properties(plot_fourier_transform
  PROPERTIES
    RUNTIME_OUTPUT_DIRECTORY "${CMAKE_CURRENT_SOURCE_DIR}/../bin"
    OUTPUT_NAME "plot_fourier_transform"
    SUFFIX ".o"
)

This is the content of my code:

#include <plot_fourier_transform/plot_fourier_transform.hpp>

int main(int argc, char** argv) {
  if (argc != 2) {
    std::cerr << "./plot_fourier_transform.o /path/to/*.wav" << std::endl;
    exit(EXIT_FAILURE);
  }
  AudioFile<double> audio_file;
  audio_file.load(argv[1]);
  audio_file.printSummary();
  int frame_size = audio_file.getNumSamplesPerChannel();
  int sample_rate = audio_file.getSampleRate();
  Gist<double> gist(frame_size, sample_rate);
  gist.processAudioFrame(audio_file.samples[0]);
  const std::vector<double>& magnitude_spectrum = gist.getMagnitudeSpectrum();
  matplotlibcpp::figure();
  matplotlibcpp::title("Magnitude Spectrum");
  matplotlibcpp::plot(magnitude_spectrum);
  matplotlibcpp::show();
}

This is the header file plot_fourier_transform.hpp:

#define INCLUDE_PLOT_SOUND_WAVE_HPP_

#include <iostream>
#include <vector>

#include <AudioFile.h>
#include <matplotlibcpp.h>

#endif // INCLUDE_PLOT_SOUND_WAVE_HPP_
#ifndef INCLUDE_PLOT_SOUND_WAVE_HPP_
#define INCLUDE_PLOT_SOUND_WAVE_HPP_

#include <iostream>
#include <vector>

#include <AudioFile.h>
#include <matplotlibcpp.h>

#endif // INCLUDE_PLOT_SOUND_WAVE_HPP_

Here is the error I received. It seems the linker cannot find kiss_fft library correctly. I tried to add #define USE_KISS_FFT by brute force, but cmake tells me that USE_KISS_FFT is already defined if I do it this way.

Would you be able to help me figure out what is going on?

I figured it out
It turns out that I didn't add the CMakeLists.txt for the kiss_fft library
