[CMake] My nomination for least helpful CMake Error Message (CONFIGURE_FILE issue)

[David Cole]

Perhaps you need a "*" before .xpm and .gif?
Perhaps the input files do not exist in "${SGICOMMONLIB_SOURCE_DIR}/"?
Perhaps you don't have write permission in
"${CMAKE_RUNTIME_OUTPUT_DIRECTORY}/${DIRNAME}/" ?

For best results, I'd recommend using something like:
> FILE(GLOB DEFAULT_CONFIG_FILES "${full_dir_name}/*.xbm"
"${full_dir_name}/*.xpm" "${full_dir_name}/*.gif" "${full_dir_name}/*.tif"
"${full_dir_name}/*.pal" )

If you do not have the directory name in the globbing expression, then there
is an implied dir that it runs in... I am not sure if that implied dir is
CMAKE_CURRENT_SOURCE_DIR or current working directory or something else,
because I always use full path directory names in file glob input
expressions...


(But I will grant you that "Problem configuring file" is a pretty lame error
message...) :-)

HTH,
David
