The target name has scope in the directory in which it is created and below, but the GLOBAL option extends visibility. Is this required in order for adjacent ExternalProject’s to be able to also link to these targets? Or is global serving a different purpose? The docs say I notice the hdfortran project uses GLOBAL when declaring it’s library targets. These examples could be further optimized, but give examples of each in somewhat widely used projects. This one uses two externalProjects to build Zlib and HDF5, if they’re not found: h5fortran/CMakeLists.txt at main Īnother example using Git submodule: p4est/CMakeLists.txt at prev3-develop įetchContent if lapack not found: scalapack/lapack.cmake at master

#Cmake install directory without subdirectories code

# if external project, additional code to specify targets from that project

#Cmake install directory without subdirectories update

# fetchcontent, external project, or git submodule update I do follow like your pattern: find_package(Foo) Requires extra code in your project to declare libraries from the other project. ExternalProject: Can build other project (autotools, makefile, etc) without mingling scope.Intermingles scope as well–better for external projects that you control or understand thoroughly

#Cmake install directory without subdirectories download

FetchContent: instead of a Git submodule, use Git or cURL or similar to download other Cmake project.

Intermingles scope like a conventional subdirectory

add_subdirectory: can be used if the other project is a Git submodule or similar of your main project.

The way I understand it is the following (I would greatly appreciate clarity/correction from others too): There are multiple ways to approach this, each with their own tradeoffs. Or should I make my own FindPacakge.cmake files per each dependency and have this cmake script look in the install path for the library and build it if it doesn’t exist from inside this FindPackage script itself? I’m not sure whats best approach or what is latest way to do this.Īnd finally, what is the best way to build an external project? add_subdirectory if it supports cmake? ExternalProject_Add() if it doesn’t support cmake? Or include path/to/project/Config.cmake if it exists? Target_link_libraries(prj PackageName::Libraries) I am wondering if this is a valid pattern below? find_package(PackageName) This means I will compile a lot of dependencies my self. Ultimately I would like to be able to do find my dependencies in the CMAKE_INSTALL_PREFIX and make sure to have reproducible builds and not use system libraries. I’m having trouble distinguishing the best way to include dependencies.
