See the cmake-developer(7) manual for more information about creatingĪ config-file package consists of a Package Configuration File and Similarly there is no _DIR variable,īut each of the artifacts such as library locations and header file locations ItĬan still be expected to be set by convention however and should be set by Variable is not automatically set by the find_package() command. Of reference identifies the package as being found, so the _FOUND Unlike the case of an upstream-provided package configuration file, no single point Unlike a package configurationįile, it is not shipped with upstream, but is used by downstream to find theįiles by guessing locations of files with platform-specific hints. Is needed when the upstream is not built with CMake, or is not CMake-awareĮnough to otherwise provide a package configuration file. Find-module Packages ¶Ī find module is a file with a set of rules for finding the required pieces ofĪ dependency, primarily header files and libraries. The _DIR cache variable is set to the location of the Variable is set to true or false, depending on whether the package wasįound. Provided to assist downstreams in using the package.Ī set of variables which provide package status information are also setĪutomatically when using a config-file package. Packages, that is, they belong with the header files and any other files
The most simple way forĪ CMake user to tell cmake(1) to search in a non-standard prefix forĪ package is to set the CMAKE_PREFIX_PATH cache variable.Ĭonfig-file packages are provided by upstream vendors as part of development CMake searches in a number of locations for package configuration files, asĭescribed in the find_package() documentation. TRUE, the package will not be searched, and will alwaysĬMAKE_REQUIRE_FIND_PACKAGE_ to TRUE will make theĪ config-file package is a set of files provided by upstreams for downstreams

Using find_package() is either a set of IMPORTED targets, orĪ set of variables corresponding to build-relevant information. PackagesĪre found with the find_package() command.
