Whats your is? It doesn't seem you have libogg installed

I think you need to install libogg-dev

sudo apt-get update
sudo apt-get install libogg-dev

[seitzbg]

It is installed:

dpkg -L libogg-dev |grep libogg.so
/usr/lib/x86_64-linux-gnu/libogg.so

[purpl3F0x]

The fact that you have the .so doesn't mean you can compile code with lib off. You need the libogg-dev for the header files

[seitzbg]

Ya it has both installed :(

[purpl3F0x]

Maybe if you change OGG to ogg in the last cmake command?

Hmm, If you add -lstdc++fs on the compiler options ?

[seitzbg]

This seemed to help in the CMakeLists

find_library(OGG NAMES FLAC FLAC++ stdc++fs)

target_link_libraries(${PROJECT_NAME} FLAC++ FLAC ogg stdc++fs)
