Set(QT_CREATOR_SKIP_PACKAGE_MANAGER_SETUP ON) Qt Creator’s auto-setup.cmake will first look in the source directory after a file named QtCreatorPackageManager.cmake, if found then it’s included.įor the CMake only package manager cpp-pm/hunter we can have a QtCreatorPackageManager.cmake which looks like this: set(HUNTER_PACKAGES fmt)įetchContent_Declare(cpp-pm-setup GIT_REPOSITORY ) If you don’t want the vcpkg auto-setup, you can set the CMake variable QT_CREATOR_SKIP_VCPKG_SETUP to TRUE. Conan has generated a conanbuildinfo.cmake file (corresponding with the cmake generator) with all the information about the libcurl dependency and all the transitive ones, in this case, OpenSSL and ZLib, and some macros we can call to ease the task of linking with our dependencies.

Package manager auto-setupĬMake, starting with version 3.15, allows injecting custom code without modifying the project CMake source code via CMAKE_PROJECT_INCLUDE_BEFORE. The setup of the package manager could be done in CMake code, by hard coding specific code, or by documenting how the environment needs to be setup before configuring the CMake project. This is the integration that will become the standard one in Conan 2.0, and the. This is where a package manager comes into play. The new, experimental integration with CMake can be found in.
