Hi there!
Thanks a lot for your amazing program but I am facing a problem when I want to execute the build as below:-
cmake --build . --config Release
Scanning dependencies of target xml_generator
[ 50%] Building CXX object src/CMakeFiles/xml_generator.dir/main.cc.o
[100%] Linking CXX executable ../bin/xml_generator

make[1]: *** [src/CMakeFiles/xml_generator.dir/all] Error 2

make: *** [all] Error 2

Please advice

Had the same problem, by adding the following line into dlib-to-tf-keras-converter/xml_generator/cmake/FindDlib.cmake after find_package(GIF), it solved it for me

SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11 -pthread")
