Undefined reference to libraries while building

I am trying to install tgs2apng in Ubuntu on WSL. As instructed I installed the 3 libraries- rlottie, libpng and apngasm. However When I run make I get undefined references to rlottie and apngasm

Here's the output of make

g++ -Wl,--start-group -lrlottie -lapngasm -lboost_filesystem -lboost_regex -Wl,--end-group -Wl,-rpath-link=/usr/local/lib    tgs2apng.cpp   -o tgs2apng

ldconfig -p | grep rlottie returns-

  librlottie.so.0 (libc6,x86-64) => /lib/librlottie.so.0
  librlottie.so (libc6,x86-64) => /lib/librlottie.so
  librlottie-image-loader.so (libc6,x86-64) => /lib/librlottie-image-loader.so

and ldconfig -p | grep apngasm returns-

  libapngasm.so (libc6,x86-64) => /usr/local/lib/libapngasm.so

I think that means the libraries are installed, can anyone point out the cause of this error?
