if you use target compile-options in one of your projects named foo and also use compile-options as a target in another project named bar, then when using foo and bar in the same project, one of the add_library(compile-options INTERFACE) commands will fail because the target compile-option already exists.
A prefix is not necessary but prevents potential conflicts with other targets, e.g. NOTE: in below, replace foo- with your project name or custom prefix. If the CMake output includes error message(s) stating that the target platform does not support dynamic linking, this may be resolved by executing export CRAYPE_LINK_TYPE=dynamic.
It is possible to provide the path to the required libraries using the variable CMAKE_PREFIX_PATH in cases where cmake fails to find them on its own, e.g. In order to "use" interface libraries, just "link" the interface library against the target you want the properties to build properties to be applied to. include paths, build flags, link flags, link libraries, compile definitions, etc. "INTERFACE" libraries are libraries that do not create an output but instead hold specific build features, e.g. cmake -DCMAKE_SYSTEM_NAME=CrayLinu圎nvironment.
#Cmake set cxx flags generator#
It is build-system generator - on NERSC machines, CMake will generate UNIX Makefiles, by default - and there is no need to enable CMake in cross-compilation mode, e.g.
CMake is an open-source, cross-platform family of tools designed to build, test, and package software.
