"This command is used to find a SEARCH_XXX_DESC. "
"A cache entry named by <VAR> is created to store the result "
"of this command. "
"If the SEARCH_XXX is found the result is stored in the variable "
"and the search will not be repeated unless the variable is cleared. "
"If nothing is found, the result will be "
"<VAR>-NOTFOUND, and the search will be attempted again the "
"next time FIND_XXX is invoked with the same variable. "
"The name of the SEARCH_XXX that "
"is searched for is specified by the names listed "
"after the NAMES argument. Additional search locations "
"can be specified after the PATHS argument. If ENV var is "
"found in the PATHS section the environment variable var "
"will be read and converted from a system environment variable to "
"a cmake style list of paths. For example ENV PATH would be a way "
"to list the system path variable. The argument "
"after DOC will be used for the documentation string in "
"the cache. PATH_SUFFIXES can be used to give sub directories "
"that will be appended to the search paths.\n"
"If NO_DEFAULT_PATH is specified, then no additional paths are "
"added to the search. "
"If NO_DEFAULT_PATH is not specified, the search process is as follows:\n"
"1. Search cmake specific environment variables. This "
"can be skipped if NO_CMAKE_ENVIRONMENT_PATH is passed.\n"
""
" CMAKE_FRAMEWORK_PATH\n"
" CMAKE_APPBUNDLE_PATH\n"
" CMAKE_XXX_PATH\n"
"2. Search cmake variables with the same names as "
"the cmake specific environment variables. These "
"are intended to be used on the command line with a "
"-DVAR=value. This can be skipped if NO_CMAKE_PATH "
"is passed.\n"
""
" CMAKE_FRAMEWORK_PATH\n"
" CMAKE_APPBUNDLE_PATH\n"
" CMAKE_XXX_PATH\n"
"3. Search the standard system environment variables. "
"This can be skipped if NO_SYSTEM_ENVIRONMENT_PATH is an argument.\n"
" PATH\n"
" XXX_SYSTEM\n" // replace with "", LIB, or INCLUDE
"4. Search cmake variables defined in the Platform files "
"for the current system. This can be skipped if NO_CMAKE_SYSTEM_PATH "
"is passed.\n"
" CMAKE_SYSTEM_FRAMEWORK_PATH\n"
" CMAKE_SYSTEM_APPBUNDLE_PATH\n"
" CMAKE_SYSTEM_XXX_PATH\n"
"5. Search the paths specified after PATHS or in the short-hand version "
"of the command.\n"
"On Darwin or systems supporting OSX Frameworks, the cmake variable"
" CMAKE_FIND_FRAMEWORK can be set to empty or one of the following:\n"
" \"FIRST\" - Try to find frameworks before standard\n"
" libraries or headers. This is the default on Darwin.\n"
" \"LAST\" - Try to find frameworks after standard\n"
" libraries or headers.\n"
" \"ONLY\" - Only try to find frameworks.\n"
" \"NEVER\". - Never try to find frameworks.\n"
"On Darwin or systems supporting OSX Application Bundles, the cmake "
"variable CMAKE_FIND_APPBUNDLE can be set to empty or one of the "
"following:\n"
" \"FIRST\" - Try to find application bundles before standard\n"
" programs. This is the default on Darwin.\n"
" \"LAST\" - Try to find application bundles after standard\n"
" programs.\n"
" \"ONLY\" - Only try to find application bundles.\n"
" \"NEVER\". - Never try to find application bundles.\n"
"The CMake variable CMAKE_FIND_ROOT_PATH specifies one or more "
"directories which will be prefixed to all of the search directories. "
"By default it is empty. It is especially useful when "
"cross-compiling to point to the root directory of the "
"target environment and CMake will search there too. By default at first "
"the directories listed in CMAKE_FIND_ROOT_PATH and then the non-prefixed "
"directories will be searched. "
"The default behavior can be adjusted by setting "
"CMAKE_FIND_ROOT_PATH_MODE_XXX. This behavior can be manually "
"overridden on a per-call basis. "
"By using CMAKE_FIND_ROOT_PATH_BOTH the search order will "
"be as described above. If NO_CMAKE_FIND_ROOT_PATH is used "
"then CMAKE_FIND_ROOT_PATH will not be used. If ONLY_CMAKE_FIND_ROOT_PATH "
"is used then only the prefixed directories will be searched.\n"
"The reason the paths listed in the call to the command are searched "
"last is that most users of CMake would expect things to be found "
"first in the locations specified by their environment. Projects may "
"override this behavior by simply calling the command twice:\n"
" FIND_XXX(<VAR> NAMES name PATHS paths NO_DEFAULT_PATH)\n"
" FIND_XXX(<VAR> NAMES name)\n"
"Once one of these calls succeeds the result variable will be set "
"and stored in the cache so that neither call will search again.";
