I've not had a problem with this before, but I'm having an odd issue where cmake is finding libpng when it doesn't exist on an OSX machine.
I'm using Findlibpng.cmake: include(LibFindMacros) find_path(LIBPNG_INCLUDE_DIR NAMES png.h PATHS ${LIBPNG_PKGCONF_INCLUDE_DIRS}) find_library(LIBPNG_LIBRARY NAMES png PATHS ${LIBPNG_PKGCONF_LIBRARY_DIRS}) set(LIBPNG_PROCESS_INCLUDES LIBPNG_INCLUDE_DIR) set(LIBPNG_PROCESS_LIBS LIBPNG_LIBRARY LIBPNG_LIBRARIES) libfind_process(LIBPNG) And in my cmake file: FIND_PACKAGE(libpng REQUIRED) When I run cmake it says it found LIBPNG (cmake-gui doesn't request I search for the path manually) and when compile it's erroring: [ 74%] Built target test_sethandler make[2]: *** No rule to make target `/usr/local/lib/libpng.dylib', needed by `tests/na/common/test_common'. Stop. make[1]: *** [tests/na/common/CMakeFiles/test_common.dir/all] Error 2 The obvious reason is that /usr/local/lib/libpng.dylib doesn't exist: arc:mbuild douglasl$ ls /usr/local/lib/ | grep png arc:mbuild douglasl$ But my cmake cache shows: LIBPNG_INCLUDE_DIR:PATH=/Library/Frameworks/Mono.framework/Headers LIBPNG_LIBRARY:FILEPATH=/usr/local/lib/libpng.dylib //ADVANCED property for variable: LIBPNG_INCLUDE_DIR LIBPNG_INCLUDE_DIR-ADVANCED:INTERNAL=1 //ADVANCED property for variable: LIBPNG_LIBRARY LIBPNG_LIBRARY-ADVANCED:INTERNAL=1 Can someone shed some light on how cmake is finding that module? Sounds like the machine config is broken, but I'm not sure exactly how to fix it. Cheers, Doug.
