[CMake] linker default library path /usr/local/lib on OSX

[Michael Jackson]

My guess is that the audio library has an install path of /usr/local/lib
encoded in it. Try posting tue output of otool for the actual audio
library.

ok i get your point.
mmm. In others words you need something equivalent to rpath command, im
pretty sure cmake can handle this easily let me know if the following helps.

have you tried adding more options to the find_library command ??
for example have you tried this (also, with the PATHS command just to be
sure):

find_library(IrrKlang_LIBRARIES irrKlang
PATHS
${CMAKE_CURRENT_SOURCE_DIR}/Dependencies/IrrKLangAudioEngine/bin/macosx-gcc
 NO_DEFAULT_PATH
 )

And what is your "target_link_libraries" command?
