Question

I’ve set LIBRARY_SEARCH_PATHS to /opt/local/lib, and verified that the library in question is there (I’m linking to GLEW):

$ls /opt/local/lib  libGLEW.1.5.1.dylib libfreetype.a       libz.a libGLEW.1.5.dylib   libfreetype.dylib   libz.dylib libGLEW.a       libfreetype.la      pkgconfig libGLEW.dylib       libz.1.2.3.dylib libfreetype.6.dylib libz.1.dylib 

but Xcode gives me the linker error

library not found for -lGLEW 

I’m generating the Xcode project with CMake, so I don’t want to explicitly modify the Xcode project (if someone suggests adding it as a framework, or something like that). Xcode recognizes USER_HEADER_SEARCH_PATHS fine (as in this question); why doesn’t it work here?

Answer 1

Perhaps adding something like this to your CMakeLists.txt?

find_library(GLEW_LIB GLEW /opt/local/lib) if(NOT ${GLEW_LIB})   message(FATAL_ERROR 'Could not find GLEW') endif() target_link_libraries(myprogram ${GLEW_LIB} ...) 

Where myprogram is the name of the target executable that needs to link with the library. You would replace the … with the other libraries you are using on that executable.

This way CMake would handle the library path details for you.
