That's weird, since cmake checks for existing files.
Maybe that file existed before and has been removed, but it is still in the
cmake cache ?
What does libfind_process() do, what is LibFindMacros.cmake for a file ?

[CMake] How does cmake find libraries?
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.
