¿Qué es Find_package?

What is Find_package?

Package File Interface Variables. When loading a find module or package configuration file find_package defines variables to provide information about the call arguments (and restores their original state before returning): CMAKE_FIND_PACKAGE_NAME. The which is searched for.

FIND_PACKAGE() asks CMake to find and load settings from the external package . This works as follows: CMake searches the directories listed in CMAKE_MODULE_PATH for a file called Find.

This tutorial shows how to export a CMake library to a package and import it from a different project using the find_package () command. This works faster as referencing the library project’s directory using the add_subdirectory () command, as the exporting mechanism allows precisely selecting which targets to export.

This guide and the complete example source code can be found in the Help/guide/importing-exporting directory of the CMake source code tree. IMPORTED targets are used to convert files outside of a CMake project into logical targets inside of the project.

You can fix this by adding “c://Packages//DemoLibraryClient” to the “Extra module directories” field on the CMake Project Settings page of VisualGDB Project Properties for your project: Now CMake will find the package and build the project, however running it will result in an error: the libCMakeLibraryDemo.so file will not be found:

If we don’t do this, when CMake creates the export information it will export a path that is specific to the current build directory and will not be valid for other projects. We can use generator expressions to specify that if we’re building the library include the current source directory. Otherwise, when installed, include the include directory.
