Other names for the result-variable are not +# allowed. So for a Find-module named FindFooBar.cmake, the two +# possible names are FooBar_FOUND and FOOBAR_FOUND. It is recommended +# to use the original case version. If the FOUND_VAR option is not +# used, the default is <UPPERCASED_NAME>_FOUND. +# +# As in the simple mode, if <var1> through <varN> are all valid, +# <packagename>_FOUND will be set to TRUE. After REQUIRED_VARS the +# variables which are required for this package are listed. Following +# VERSION_VAR the name of the variable can be specified which holds the +# version of the package which has been found. If this is done, this +# version will be checked against the (potentially) specified required +# version used in the find_package() call. The EXACT keyword is also +# handled. The default messages include information about the required +# version and the version which has been actually found, both if the +# version is ok or not. If the package supports components, use the +# HANDLE_COMPONENTS option to enable handling them.

Use the option +# CONFIG_MODE if your FindXXX.cmake module is a wrapper for a +# find_package(... NO_MODULE) call. In this case VERSION_VAR will be +# set to <NAME>_VERSION and the macro will automatically check whether +# the Config module was found.

If it is +# found, success will be reported, including the content of <var1>. On +# repeated Cmake runs, the same message won't be printed again. +# +# Example for mode 2: +# +# :: +# +# find_package_handle_standard_args(LibXslt +# FOUND_VAR LibXslt_FOUND +# REQUIRED_VARS LibXslt_LIBRARIES LibXslt_INCLUDE_DIRS +# VERSION_VAR LibXslt_VERSION_STRING) +# +# In this case, LibXslt is considered to be found if the variable(s) +# listed after REQUIRED_VAR are all valid, i.e. LibXslt_LIBRARIES and +# LibXslt_INCLUDE_DIRS in this case.

It is set - * up so that output is sent to a memory buffer, which is emptied from - * the host side - but only after a cudaThreadSynchronize() on the host. - * - * Currently, there is a limitation of around 200 characters of output - * and no more than 10 arguments to a single cuPrintf() call. Issue - * multiple calls if longer format strings are required. - * - * It requires minimal setup, and is *NOT* optimised for performance. - * For example, writes are not coalesced - this is because there is an - * assumption that people will not want to printf from every single one - * of thousands of threads, but only from individual threads at a time. - * - * Using this is simple - it requires one host-side call to initialise - * everything, and then kernels can call cuPrintf at will.
